This change removes the duplicities of the PeerManager component:
* No more commiting PeerAdd and PeerRm log entries
* The Raft peer set is the source of truth
* Basic broadcasting is used to communicate peer multiaddresses
in the cluster
* A peer can only be added in a healthy cluster
* A peer can be removed from any cluster which can still commit
* This also adds support for multiple multiaddresses per peer

The main differences is that the new version of Raft is more strict
about starting raft peers which already contain configurations.
For a start, cluster will fail to start if the configured cluster
peers are different from the Raft peers. The user will have to
manually cleanup Raft (TODO: an ipfs-cluster-service command for it).
Additionally, this commit adds extra options to the consensus/raft
configuration section, adds tests and improves existing ones and
improves certain code sections.
