This takes advantange of the latest features in go-cid, peer.ID and
go-multiaddr and makes the Go types serializable by default.
This means we no longer need to copy between Pin <-> PinSerial, or ID <->
IDSerial etc. We can now efficiently binary-encode these types using short
field keys and without parsing/stringifying (in many cases it just a cast).
We still get the same json output as before (with minor modifications for
Cids).
This should greatly improve Cluster performance and memory usage when dealing
with large collections of items.

`allocations` will be a comma-separated list of peer IDs on which we
want to pin. Peers in allocations are prioritized over automatically-determined
ones, but replication factors would stil be respected.

This commit adds support for OpenCensus tracing
and metrics collection. This required support for
context.Context propogation throughout the cluster
codebase, and in particular, the ipfscluster component
interfaces.
The tracing propogates across RPC and HTTP boundaries.
The current default tracing backend is Jaeger.
The metrics currently exports the metrics exposed by
the opencensus http plugin as well as the pprof metrics
to a prometheus endpoint for scraping.
The current default metrics backend is Prometheus.
Metrics are currently exposed by default due to low
overhead, can be turned off if desired, whereas tracing
is off by default as it has a much higher performance
overhead, though the extent of the performance hit can be
adjusted with smaller sampling rates.

This adds support for handling preflight requests in the REST API
and fixes currently mostly broken CORS.
Before we just let the user add custom response headers to the
configuration "headers" key but this is not the best way because
CORs headers and requests need special handling and doing it wrong
has security implications.
Therefore, I have added specific CORS-related configuration options
which control CORS behavour. We are forced to change the "headers"
defaults and will notify the users about this in the changelog.

Added filter option to `ipfs-cluster-ctl status`
When the --filter is passed, it will only fetch the peer information
where status of the pin matches with the filter value.
Valid filter values are tracker status types(i.e., "pinned",
"pin_error", "unpinning" etc), an alias of tracker status type (i.e.,
"queued" or "error"), comma separated list of tracker status type
and/or it aliases(i.e., "error,pinning")
On passing invalid filter value no status information will be shown
In particular, the filter would remove elements from []GlobalPinInfo
when none of the peers in GlobalPinInfo match the filter. If one peer
in the GlobalPinInfo matches the filter, the whole object is returned,
including the information for the other peers which may or not match it.
filter option works on statusAll("GET /pins"). For fetching pin status
for a CID("GET /pins/<cid>"), filter option would have no effect

Before we resolved all /dns*/ multiaddresses before we used them.
When using HTTPs, the Go HTTP Client only sees the resolved IP address
and it is unable to negotiate TLS with a cerficate because the request
is not going to the hostname the certificate is signed for, but to
the IP. This leverages a recent feature in go-multiaddr-net
and uses directly the user-provided hostname.

By default, CORS headers allowing GET requests from everywhere are

This commit refactors the sendResponse methods in the API, merging

the configured headers too, to make sure no route was missed.

This straigthens some mistakes with the outputs of the /add endpoints.
Currently, we had exactly the same output format which:
* was not exactly the ipfs API output format but was sort of similar
* made some weird concessions to be compatible (like having a string-type "size")
* was not aligned with Cluster API conventions (lowercase keys)
This corrects all this:
* The Cluster API /add output format now uses the right types and lowercase keys.
* `Hash` is now `Cid`, because the field carries a Cid.
* We copy error handling with request trailers from IPFS, and avoid carrying the
errors in the output objects.
* The proxy now returns exactly the types as ipfs would
* We add the X-Chunked-Output: 1 header, which is custom and redundant, but
otherwise breaks js-ipfs-api integrations with the /add endpoint.

This is a workaround to have clients behave properly with the /add
endpoint by asking them to close connections when done, effectively
disabling keep-alive for this.
This means we don't need to disable keep-alives fully on all servers,
since the rest of endpoints are not affected (they are not streaming
endpoints).

This uses go-libp2p-kad-dht as routing provider for the Cluster Peers.
This means that:
* A cluster peer can discover other Cluster peers even if they are
not in their peerstore file.
* We remove a bunch of code sending and receiving peers multiaddresses
when a new peer was added to the Cluster.
* PeerAdd now takes an ID and not a multiaddress. We do not need to
ask the new peer which is our external multiaddress nor broadcast
the new multiaddress to everyone. This will fix problems when bootstrapping
a new peer to the Cluster while not all the other peers are online.
* Adding a new peer does not mean to open connections to all peers
anymore. The number of connections will be made according to the DHT
parameters (this is good to have for future work)
The that detecting a peer addition in the watchPeers() function does
no longer mean that we have connected to it or that we know its
multiaddresses. Therefore it's no point to save the peerstore in these
events anymore.
Here a question opens, should we save the peerstore at all, and should we
save multiaddresses only for cluster peers, or for everyone known?
Currently, the peerstore is only updated on clean shutdown,
and it is updated with all the multiaddresses known, and not limited to
peer IDs in the cluster, (because, why not).

This commit promotes the Consensus component (and Raft) to become a fully
independent thing like other components, passed to NewCluster during
initialization. Cluster (main component) no longer creates the consensus
layer internally. This has triggered a number of breaking changes
that I will explain below.
Motivation: Future work will require the possibility of running Cluster
with a consensus layer that is not Raft. The "consensus" layer is in charge
of maintaining two things:
* The current cluster peerset, as required by the implementation
* The current cluster pinset (shared state)
While the pinset maintenance has always been in the consensus layer, the
peerset maintenance was handled by the main component (starting by the "peers"
key in the configuration) AND the Raft component (internally)
and this generated lots of confusion: if the user edited the peers in the
configuration they would be greeted with an error.
The bootstrap process (adding a peer to an existing cluster) and configuration
key also complicated many things, since the main component did it, but only
when the consensus was initialized and in single peer mode.
In all this we also mixed the peerstore (list of peer addresses in the libp2p
host) with the peerset, when they need not to be linked.
By initializing the consensus layer before calling NewCluster, all the
difficulties in maintaining the current implementation in the same way
have come to light. Thus, the following changes have been introduced:
* Remove "peers" and "bootstrap" keys from the configuration: we no longer
edit or save the configuration files. This was a very bad practice, requiring
write permissions by the process to the file containing the private key and
additionally made things like Puppet deployments of cluster difficult as
configuration would mutate from its initial version. Needless to say all the
maintenance associated to making sure peers and bootstrap had correct values
when peers are bootstrapped or removed. A loud and detailed error message has
been added when staring cluster with an old config, along with instructions on
how to move forward.
* Introduce a PeerstoreFile ("peerstore") which stores peer addresses: in
ipfs, the peerstore is not persisted because it can be re-built from the
network bootstrappers and the DHT. Cluster should probably also allow
discoverability of peers addresses (when not bootstrapping, as in that case
we have it), but in the meantime, we will read and persist the peerstore
addresses for cluster peers in this file, different from the configuration.
Note that dns multiaddresses are now fully supported and no IPs are saved
when we have DNS multiaddresses for a peer.
* The former "peer_manager" code is now a pstoremgr module, providing utilities
to parse, add, list and generally maintain the libp2p host peerstore, including
operations on the PeerstoreFile. This "pstoremgr" can now also be extended to
perform address autodiscovery and other things indepedently from Cluster.
* Create and initialize Raft outside of the main Cluster component: since we
can now launch Raft independently from Cluster, we have more degrees of
freedom. A new "staging" option when creating the object allows a raft peer to
be launched in Staging mode, waiting to be added to a running consensus, and
thus, not electing itself as leader or doing anything like we were doing
before. This additionally allows us to track when the peer has become a
Voter, which only happens when it's caught up with the state, something that
was wonky previously.
* The raft configuration now includes an InitPeerset key, which allows to
provide a peerset for new peers and which is ignored when staging==true. The
whole Raft initialization code is way cleaner and stronger now.
* Cluster peer bootsrapping is now an ipfs-cluster-service feature. The
--bootstrap flag works as before (additionally allowing comma-separated-list
of entries). What bootstrap does, is to initialize Raft with staging == true,
and then call Join in the main cluster component. Only when the Raft peer
transitions to Voter, consensus becomes ready, and cluster becomes Ready.
This is cleaner, works better and is less complex than before (supporting
both flags and config values). We also backup and clean the state whenever
we are boostrapping, automatically
* ipfs-cluster-service no longer runs the daemon. Starting cluster needs
now "ipfs-cluster-service daemon". The daemon specific flags (bootstrap,
alloc) are now flags for the daemon subcommand. Here we mimic ipfs ("ipfs"
does not start the daemon but print help) and pave the path for merging both
service and ctl in the future.
While this brings some breaking changes, it significantly reduces the
complexity of the configuration, the code and most importantly, the
documentation. It should be easier now to explain the user what is the
right way to launch a cluster peer, and more difficult to make mistakes.
As a side effect, the PR also:
* Fixes#381 - peers with dynamic addresses
* Fixes#371 - peers should be Raft configuration option
* Fixes#378 - waitForUpdates may return before state fully synced
* Fixes#235 - config option shadowing (no cfg saves, no need to shadow)

The --wait flag was being completely ignored unless --no-status was passed
too, which makes no sense because then it would print the wait status.
This waits when --wait and prints the status when --no-status is not passed.
If we have been waiting, the status comes from that. Otherwise we request it.

option) or it is assumed to be the same as the PeerAddr/APIAddr, with
