Review comment:
> The metric can give the user an idea of how many audit logs are being
automatically deleted. Basically how many audit logs do they have within the
duration configured. This can help them get a sense if they want to increase or
decrease the durationToRetain.
Thanks for the explanation. Could you please explain this in the doc as
well? Also please mention that this metric is emitted only when
`druid.coordinator.kill.audit.on` is set to true.

Review comment:
The doc CI fails because of `PT1H`. One way to avoid the spell check for
such variables is wrapping them with backticks (`` ` ``).
