This commit adds PeerAdd() and PeerRemove() endpoints, CLI support, tests. Peer management is a delicate issue because of how the consensus works underneath and the places that need to track such peers. When adding a peer the procedure is as follows: * Try to open a connection to the new peer and abort if not reachable * Broadcast a PeerManagerAddPeer operation which tells all cluster members to add the new Peer. The Raft leader will add it to Raft's peerset and the multiaddress will be saved in the ClusterPeers configuration key. * If the above fails because some cluster node is not responding, broadcast a PeerRemove() and try to undo any damage. * If the broadcast succeeds, send our ClusterPeers to the new Peer along with the local multiaddress we are using in the connection opened in the first step (that is the multiaddress through which the other peer can reach us) * The new peer updates its configuration with the new list and joins the consensus License: MIT Signed-off-by: Hector Sanjuan <hector@protocol.ai>
