Use information from lease WATCH system to respond to added/removed servers more quickly

[carreter]

PR #643 adds a new lease-based system for detecting the number of servers each agent should be connected to. However, a lease count is only calculated upon a new server connection request.

An improved version of this system would hook into the lease Informer's event system to initiate a new connection when a new lease is detected.
