Missing statistic explanation

https://docs.couchbase.com/server/current/cli/cbstats/cbstats-all.html

This page shows explanations for statistics.

Regarding document expiry, the following statistics are relevant:

ep_expired_access
ep_expired_pager
ep_expired_compactor

All 3 of these statistics are listed in the example output, but explanations are only given for 2 of these statistics (access and pager). There is no definition for ep_expired_compactor:

ep_item_begin_failed

Number of times a transaction failed to start due to storage errors.

ep_expired_access

Number of times an item was expired on application access.

ep_expired_pager

Number of times an item was expired by ep engine item pager.

ep_item_flush_expired

Number of times an item is not flushed due to the expiry of the item.

The missing definition should be added - ep_expired_compactor is the number of times a document was expired during compaction.
