jsonConfigs.getSection() returned a value when it needed to
return a pointer to the jsonSection fields inside the struct.
Even though the jsonSection type is a map, therefore on the heap,
returning it as a value (non-pointer) resulted in it being
disassociated with the jsonConfigs overarching struct.

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.

The JSON parsing of the config could error, but we skipped error checking and
use Validate() at the end. This caused that maybe some JSON parsing errors
where logged but the final error when validating the configuration came from
somewhere different, creating very confusing error messages for the user.
This changes this, along with removing hardcoded section lists. This also
removes a Sharder component section because, AFAIK, it was a left over
from the sharding branch and in the end there is no separate sharding
component that needs a config.

Warning about old config style(proxy inside ipfs connector) getting

We want to maintain configuration compatibility and still recognize the
proxy configuration options in the ipfshttp connector configuration
section.
Check if there is a proxy configuration section.
If not create one with the options from the ipfshttp section (if they
are defined, otherwise do nothing).
This implementation utilizes the fact that json object can be
unmarshelled to a struct whose elements are a subset of the json object

It should provide a way to speed up peer list updates when
peers join/part. It was hardcoded.

This also generates a default configuration section when it
doesn't exist, so it's backwards compatible.

There might be a case where the program is terminated before
configuration is saved.
Also, avoid calling save() multiple times on shutdowns.

The following commit reimplements ipfs-cluster configuration under
the following premises:
* Each component is initialized with a configuration object
defined by its module
* Each component decides how the JSON representation of its
configuration looks like
* Each component parses and validates its own configuration
* Each component exposes its own defaults
* Component configurations are make the sections of a
central JSON configuration file (which replaces the current
JSON format)
* Component configurations implement a common interface
(config.ComponentConfig) with a set of common operations
* The central configuration file is managed by a
config.ConfigManager which:
* Registers ComponentConfigs
* Assigns the correspondent sections from the JSON file to each
component and delegates the parsing
* Delegates the JSON generation for each section
* Can be notified when the configuration is updated and must be
saved to disk
The new service.json would then look as follows:
```json

This new format aims to be easily extensible per component. As such,
it already surfaces quite a few new options which were hardcoded
before.
Additionally, since Go API have changed, some redundant methods have been
removed and small refactoring has happened to take advantage of the new
way.
