(cherry picked from commit 3453930d438dc3ba9ba5addca59aec6786293bd4)

 Note:
    This commit was heavily modified. We wanted to provide the number of
    ipv4 and ipv6 monitors in the report, so we rewrote that part so we
    can report on it; but we had to drop everything else (msgr1 and
    msgr2), as well as 'min_mon_release'. Those do not exist in
    luminous. In the end, the commit message itself is misleading, but
    we are somehow (*shrug*) opting for leaving the commit as the original.
    Additionally, we removed PendingReleaseNotes changes to prevent
    conflicts in the future.
