Role management for the case where the controller does not hear back from
the registry-service causing the handshake to time out. Earlier we were
disconnecting the switch. With this patch, we will move to state Equal/Slave.
This behavior should be changed, once the underlying registry replies
to every mastership request (currently only replies to the controller that
wins mastership).

Also changed the timeouts:
 - role-reply not received timeout to 3 secs
 - handshake not completed timeout to 10 secs

Previously the timeouts were 10 and 60 secs respectively, which is too long
to figure out that something has gone wrong.
