* Libp2p protectors no longer needed, use PSK directly
* Generate cluster 32-byte secret here (helper gone from pnet)
* Switch to go-log/v2 in all places
* DHT bootstrapping not needed. Adjust DHT options for tests.
* Do not rely on dissappeared CidToDsKey and DsKeyToCid functions fro dshelp.
* Disable QUIC (does not support private networks)
* Fix tests: autodiscovery started working properly
I had thought of this for a very long time but there were no compelling
reasons to do it. Specifying RPC endpoint permissions becomes however
significantly nicer if each Component is a different RPC Service. This also
fixes some naming issues like having to prefix methods with the component name
to separate them from methods named in the same way in some other component
(Pin and IPFSPin).
This was a leftover. For consisency, all CIDs coming out of the API
should have the canonical cid form ( { "/": "cid" } ), otherwise
we are inconsistent.
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.

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 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.

Usually we had wrap-in-directory enabled by default because otherwise
we had an error when adding single, non-directory files.
wrap-in-directory happens automatically when adding more than one file
so that was no problem. Thigns also worked when adding a folder and Wrap was
disabled. The only case was adding a single with wrap disabled (a default option).
This patches the ipfsadd/add.go file to remember the last added file so that
we can use it's Cid as the resulting root of the adding process without
having to fetch it from our dummy dagservice.
We have to pass this CID to our Finalize() functions, because it turns out that
in this case (single file without wrap-in-directory), the last block added to the DAG
is not the IPFS root (the ipfsadd/Adder adds the mfs root folder last always).
This was the case when wrap-in-directory was enabled by default.

This removes a bunch of the channel dance and block forwarding
by having the adder submodules be DAGServices themselves and take
Add() directly from the ipfsAdder.

This was a long FIXME/TODO. Handling adding output and
reporting to the client of the progress of the adding process.
This attempts to do it. It is not sure that it works correctly
(response body being written while the multipart request is still being read)
