ssh access coordination via a central controller

Low priority.

For simpler access setup, we need only one controller machine to have access to all other machines. Any machine trying to do rpc can go via the controller machine. That way we do not need to have a setup where each machine can talk to all other machines.

We can call this a brokered architecture. This way the private key never goes out of the broker machine and communication is fully secure.
