The query metrics are actually reported for all read queries, not only
ones that use a MinIndex to block for updates.
Also clarify the raft.apply metric is only on the leader.
This PR adds cluster members to the metrics API. The number of members per
segment are reported as well as the total number of members.
Tested by running a multi-node cluster locally and ensuring the numbers were
correct. Also added unit test coverage to add the new expected gauges to
existing test cases.
