KUDU-2335. Work around rare consensus health bug for 1.7 release

In very rare circumstances we have hit a DHCECK in quorum_util.cc in
pre-commit builds stating that the leader should always have a HEALTHY
health status. We have traced this to points in the replica lifecycle
when the health status could be UNKNOWN.

Since we want to release 1.7.0 soon, let's work around this issue for
now. We'll follow up with a "real" fix and a decent test later.
