661fb0d54c 45-use-statistical-testing 
Keepalive is based on per mesh and not per node.
Using total ordering mechanism similar to paxos to elect a leader
if leader doesn't update it's timestamp within 3 * keepAlive then
give the leader a gravestone and elect the next leader.
Leader is bassed on lexicographically ordered public key.

7be11dbaa3 27-remove-client-grpc-endpoint 
Removed a client's grpc endpoint value. Client's aren't publicly
available so there is no need for a client's gRPC endpoint.
Also changed a node ID's to their public key. A node id's public
address is an issue for mobility of clients as their endpoint
is subject to change
