db4c5e0eaa fix(server/v2): set correct content-type for etcdError response

62560f9959 fix(server): add user facing remove API 
This was accidently removed as we refactored the standy stuff. Re-add this
user facing remove endpoint that matches the config endpoints.

189fece683 hack(server): notify removed peers when they try to become candidates 
A peer might be removed during a network partiton. When it comes back it
will not have received any of the log entries that would have notified
it of its removal and go onto propose a vote. This will disrupt the
cluster and the cluster should give the machine feedback that it is no
longer a member.

The term of a denied vote is MaxUint64. The notification of the removal
is a raft event. These two modification are quick heck.

In reaction to this notification the machine should shutdown. In this
case the shutdown just moves it towards becoming a standby server.
