Bug description:
  [Impact]
  This bug will cause the bucket not able to abort the multipart upload and leaving the stale multiple entries behind for those buckets which had partial multipart uploads before the resharding.

  [Test Case]
  Deploy a latest luminous(12.2.13) ceph cluter
  Create a bucket
  upload a big file (200M+) to that bucket
  Press "Ctrl + C" after several part (each part is 15M) had been uploaded
  Manually reshard the bucket to 4 shards
  Abort the multipart uploading
  Without the fix, you will not able to abort the previous uploading

  [Regression Potential]
  Low - this fix has been accept upstream in later releases since from Mimic.

  [Original Bug Report]
  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.
