* Test case creates a bunch of clusters, assigns a pin with replica factor
of n-1 to them, and removes one of the peers randomly. It then tests
to check that the number of clusters pinning the cid is n-2.
* Add warn log to let user know that due to disable_repinning option,
the cluster won't attempt to re-assign the pin.

This commits allows restapi to serve/tunnel http on a libp2p stream.
NewWitHost(...) allows to provide a libp2p host during initialization
which is then used to obtain a listener with go-libp2p-gostream.
Alternatively, if the configuration provides an ID, PrivateKey and Libp2pListenAddr,
a host is created directly by us and used to get the listener.
The protocol tag used is provided by the p2phttp library which will
be used by the client.
All tests now run against the libp2p node too.

NewCluster() now takes an optional Host parameter.
The rationale is to allow to re-use an existing libp2p Host
when creating the cluster.
The NewClusterHost method now allows to create a host
with the options used by cluster.

This PR replaces ReplicationFactor with ReplicationFactorMax
and ReplicationFactor min.
This allows a CID to be pinned even though the desired
replication factor (max) is not reached, and prevents triggering
re-pinnings when the replication factor has not crossed the
lower threshold (min).

This enables support for testing in jenkins.
Several minor adjustments have been performed to improve the probability
that the tests pass, but there are still some random
problems appearing with libp2p conections not becoming available or
stopping working (similar to travis, but perhaps more often).
MacOS and Windows builds are broken in worse ways (those issues will
need to be addressed in the future).
Thanks to @zenground0 and @victorbjelkholm for support!

I've modified the peer identifier to be 'peername'. I've also
modified the TestLoadJSON to check that it is correctly read from
config and set to a default if empty.
Also added 'peername' fields to configurations for various tests.
This also generates a default configuration section when it
doesn't exist, so it's backwards compatible.

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.

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.

It turns out they only worked in round seconds. Tests send a metric
every second, so sometimes they were expired right away.

This is a better approach than broadcasting everything all the time
(see 6ee0f3bead). A couple of delays
have been touched in order to make tests less likely to fail randomly.

There was a bug in the test for re-allocation which hid another
bug in the re-allocation process where a pin which needs to be
re-allocated would only be assigned to the new destinations and not
anymore to the valid allocations it had previously
