The monitors may report either positive or negative clock skews, and by
not using an absolute value we were constantly ignoring reported negative
clock skews.

... even if we didn't get a clean/finished result from the monitors
This ought to significantly cut the waiting time if something else (or
someone else) is leaving the leader hanging thus unable to finish a given
timecheck round.

We were kicking-off the timeout as soon as we started; it's better however
to kick if off only when we are told to stop (as long as 'at-least-once'
is true).

at-least-once Runs at least once, even if we are told to stop.
(default: True)
at-least-once-timeout If we were told to stop but we are attempting to
run at least once, timeout after this many
seconds. (default: 300)

Will run for as long as teuthology runs. By default, fails if any clock
skews higher than 0.05 seconds are detected, but will only fail when the
teuthology run finishes and after reporting a list of all the detected
skews.
Accepted options:
interval amount of seconds to wait in-between checks. (default: 30.0)
max-skew maximum skew, in seconds, that is considered tolerable
before issuing a warning. (default: 0.05)
expect-skew 'true' or 'false', to indicate whether to expect a skew
during the run or not. If 'true', the test will fail if no
skew is found, and succeed if a skew is indeed found; if
'false', it's the other way around. (default: false)
never-fail Don't fail the run if a skew is detected and we weren't
expecting it, or if no skew is detected and we were
expecting it. (default: False)
