fix: switch ratelimiter to MonotonicClock ( #167 )
...
There is a known bug that `quanta` clock
used by default sometimes jumps back:
<https://github.com/metrics-rs/quanta/issues/111 >.
This results in `governor` rate limiter
incorrectly rejecting the messages
even when less than the configured burst size
has been sent.
Switched to standard monotonic clock
which does not have this problem.
I tested that this fixed the problem for me,
chatmail relay test `test_exceed_rate_limit`
stopped failing randomly.
