The main container will now run only ipfs-cluster-service.
A new ipfs-cluster-bundle container is built by Dockerfile-bundle
which will provide ipfs-cluster+ipfs.

ipfs-cluster-service now has a migration subcommand that upgrades
persistant state snapshots with an out-of-date format version to the
newest version of raft state. If all cluster members shutdown with
consistent state, upgrade ipfs-cluster, and run the state upgrade command,
the new version of cluster will be compatible with persistent storage.
ipfs-cluster now validates its persistent state upon loading it and exits
with a clear error in the case the state format version is not up to date.
Raft snapshotting is enforced on all shutdowns and the json backup is no
longer run. This commit makes use of recent changes to libp2p-raft
allowing raft states to implement their own marshaling strategies. Now
mapstate handles the logic for its (de)serialization. In the interest of
supporting various potential upgrade formats the state serialization
begins with a varint (right now one byte) describing the version.
Some go tests are modified and a go test is added to cover new ipfs-cluster
raft snapshot reading functions. Sharness tests are added to cover the
state upgrade command.
Also, start removing mentions of `PeerAdd` operation, as things should
happen with `--bootstrap` (Join). PeerAdd should not be part of the user
workflow and might disappear or be hidden in the future.

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.
