Avoid RPC notify_conductor_resume_{deploy,clean} in agent_base
Currently we use an RPC call to the conductor itself to proceed to the
next clean or deploy step. This is unnecessary and requires temporary
lifting the lock, potentially causing race conditions.
This change makes the agent code use continue_node_{deploy,clean}
directly. The drivers still need updating, it will be done later.
