-----------------------------------

Is this a dup of KUDU-1504?

> Add the ability to force an “unsafe” configuration change via RPC to the leader. Instead of specifying AddServer() or RemoveServer(), which enforce one-by-one configuration changes due to their inherent contract, we could specify an unsafe configuration change API for administrative / emergency cases only that the leader would process without going through the normal "one by one" safety checks required by the Raft dissertation config change protocol.
> The leader should still reject configuration changes in which is it not a member of the requested new configuration.
