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.

Optimized filter to tracker status matching by using bitwise
comparisions
License: MIT
Signed-off-by: Kishan Mohanbhai Sagathiya <kishansagathiya@gmail.com>
Added a fail case where an invalid filter is passed in.
Update `api.rpcClient.Call` to `api.rpcClient.CallContext` and pass
in the Request context r.Context() so that context can be cancelled
when the request is cancelled by caller
Fixes#445

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

Move ctl-health sharness tests to apprpriate file
Since the API is using the RPC mock to request metrics and it always
returns a mocked test metric we might just do c.Metrics("somemetricstype")
and check that there is no error. Here we just want to check that the
client is hitting an API endpoint (and understands the response).

We should deprecate passing in Host/Port in the config,
but in the meantime, it hardcoded /dns4/, meaning that if
someone placed an ipv6 address in there things would break badly
and weirdly.

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.

Issue #572 exposes metrics but they carry the peer ID in binary.
This was ok with our internal codecs but it doesn't seem to work
very well with json, and makes the output format unusable.
This makes the Metric.Peer field a string.
Additinoally, fixes calling the command without arguments and displaying
the date in the right format.

Support the new endpoint for later metrics in `rest/api/client`
Support the new method created in `rest/api/client` in
ipfs-cluster-ctl. i.e. `ipfs-cluster-ctl health metrics <name>` would
show the peers and the last list of metrics logged for each as returned
by the Peer Monitor, in a friendly way.
