The first stage is a renewal, unicast to the server.
If that fails, then later the client will start broadcasting it's
renewal requests - there may be another server that can renew it.
If that fails, then on lease expiration the client is required to
stop using the lease. It's only option is to start broadcasting
Discover messages to find a server.
