Title:
  rgw: unable to abort multipart upload after the bucket got resharded

Status in ceph package in Ubuntu:
  Fix Released
Status in ceph source package in Bionic:
  Triaged

Bug description:
  There is a bug during the resharding for those multipart entries.
  For all the multipart entries, the hash source should be the object name so that all those entries can still be
  distributed to one same bucket index shard object.
  Right now the code just calculate the shard id based on each entry's name, which is wrong

  This can cause the bucket not able to abort the multipart upload and
  leave the stale multiple entries behind.

  The fix is already merged into the mimic and nautilus. but upstream
  didn't backport it to luminous

  fix is here https://github.com/ceph/ceph/pull/32617
  upstream bug report: https://tracker.ceph.com/issues/43583
