- Ability to run a command pre up and post down
- Ability to be a client in one mesh and a peer in the other
- Added dev card to specify different sync rate, keepalive rate per
mesh.
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.
