Description

Metadata entries and their versions are being archived in the metadata_heap pool (.rgw.meta), but nothing is actually consuming this data. This archival should be made optional so that users can avoid paying the cost of creating and storing this data.

Example of metadata pool constantly increasing in size and number of objects:

NAME                          ID     USED      %USED     MAX AVAIL     OBJECTS
...
default.rgw.buckets.data 17 3092G 0.86 345T 2013585
...
default.rgw.meta 25 743M 0 172T 1975937

This is in 10.2.2-508-g9bfc0cf (9bfc0cf178dc21b0fe33e0ce3b90a18858abaf1b)
