Add retention for file request logs

[a2l007]

Description

This PR adds a new property druid.request.logging.durationToRetain that provides support to specify retention periods for request logs stored on disk. This property works only for the file-based request logger and the retention period must be at least 1 day so that it avoids deleting the request log for the current day. It is disabled by default to preserve existing behavior.

This LGTM. Crazy that file request logger has been around this long with no automatic cleanup being contributed back by a user who accidentally filled up their logging partition with request logs

Thanks for the review @capistrant !
Since the build wasn't run recently, let me re-run it before merge.

I see
this.durationToRetain == null || this.durationToRetain.compareTo(Duration.standardDays(1)) >= 0, "request logs retention period must be atleast P1D"
Shouldnt it be
this.durationToRetain.compareTo(Duration.standardDays(1)) <= 0 ?

We want durationToRetain to be more than a day right? Then why throw error-comment when its more than a day?
