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:
* Does not collect and return changed items when doing StateSync (they are
not used)
* Removes the StateSync RPC method (no longer used)
* Uses tracker.StatusAll() rather than requesting Status on each Cid (should
be faster with upcoming pintracker)
* Does not launch a go-routine to track every item. Track is an async
operation. This likely causes 1000s goroutines to be started with no good
reason.

This allows to call the Rest API's status and sync endpoints with a
"?local=true" parameter. This will trigger operations but only on the
local peer. Cluster *Local and RPC-*Local methods have been accordingly,
although they are aliases for the PinTracker methods (but otherwise they
would not be exposed in external APIs). ipfs-cluster-ctl has been updated to
support the new flag.
The rationaly behind this feature is that sometimes, a single cluster peer
(or the ipfs daemon in it) is misbehaving. The user then wants to Sync,
Recover, or see Status for that single peer. This is specially relevant
when working with big pinsets in larger clusters, as a Status() call will
be considerably more expensive when broadcasted everywhere.
Note that the Rest API keeps returning GlobalPinInfo objects even on local=true
calls. This ensures that the user always gets the same datatype from an endpoint.

This adds API, RPC calls to support RecoverAllLocal() (and expose RecoverLocal()
on the Rest API too). cluster-ctl is updated accordingly.

This change removes the duplicities of the PeerManager component:
* No more commiting PeerAdd and PeerRm log entries
* The Raft peer set is the source of truth
* Basic broadcasting is used to communicate peer multiaddresses
in the cluster
* A peer can only be added in a healthy cluster
* A peer can be removed from any cluster which can still commit
* This also adds support for multiple multiaddresses per peer

The main differences is that the new version of Raft is more strict
about starting raft peers which already contain configurations.
For a start, cluster will fail to start if the configured cluster
peers are different from the Raft peers. The user will have to
manually cleanup Raft (TODO: an ipfs-cluster-service command for it).
Additionally, this commit adds extra options to the consensus/raft
configuration section, adds tests and improves existing ones and
improves certain code sections.

I have updated API endpoints to be /allocations rather than /pinlinst
It's more self-explanatory.

The disk informer uses "ipfs repo stat" to fetch the RepoSize value and
uses it as a metric.
The numpinalloc allocator is now a generalized ascendalloc which
sorts metrics in ascending order and return the ones with lowest
values.

CidArg used to be an internal name for an argument that carried a Cid.
Now it has surfaced to API level and makes no sense. It is a Pin. It
represents a Pin (Cid, Allocations, Replication Factor)

New PeerManager, Allocator, Informer components have been added along
with a new "replication_factor" configuration option.
First, cluster peers collect and push metrics (Informer) to the Cluster
leader regularly. The Informer is an interface that can be implemented
in custom wayts to support custom metrics.
Second, on a pin operation, using the information from the collected metrics,
an Allocator can provide a list of preferences as to where the new pin
should be assigned. The Allocator is an interface allowing to provide
different allocation strategies.
Both Allocator and Informer are Cluster Componenets, and have access
to the RPC API.
The allocations are kept in the shared state. Cluster peer failure
detection is still missing and re-allocation is still missing, although
re-pinning something when a node is down/metrics missing does re-allocate
the pin somewhere else.
