- 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.
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
