KUDU-2309: /masters can show the wrong list of masters
The ListMasters RPC (on which the /masters page is based) returned
masters based on the -master_addresses flag. It should return masters
based on the consensus configuration. Since we verify the two sets of
addresses are the same at startup, this usually makes no difference.
However, if a master is replaced by a server with a new UUID,
previously we would report the new UUID, even though it may not be
part of the previously established quorum. This patch adds an
additional check that the UUIDs match, and returns an error along with
the registration information if there is a mismatch.
