If the leader is the one with the accurate clock, it can still
form quorum, but if the leader has the skewed clock, all other mons appear
skewed from its perspective and no quorum is formed. This leads to
intermittent failures, depending on the non-deterministic teuthology
deployment order and how the mon IPs sort.
Fix by reducing the skew. This is enough skew to trigger a warning, but
not enough that it will break quorum. This ensures that the parts of the
teuthology test that issue random mon commands won't fail (e.g., 'ceph osd
dump').

This utilizes the recent feature in teuthology [1] to skip hidden files in
suites when building the job matrix.
Idea of this change is to enable referring to the top-level qa directory in a
position-independent way such that copies of a suite to another location do not
break any symlinks.

grep: Unmatched ( or \(
because we pass the whitelisted string to `egrep -v "$1"` directly.

This lets us run multiple cleanup steps right before ceph
teardown.
Note that we drop the facet from multimon/ because it
doesn't factor out cluster creation before this step
properly. That's fine because the require_luminous
cleanup shouldn't be related to the multimon tests.

parameter to ceph_clock_now() and ceph::real_clock::now() that carries
