Enable ListMultipartUploads and ListObjectParts for FS (#4996)
Enable ListMultipartUploads and ListObjectParts for FS (#4996)

* Enable ListMultipartUploads and ListObjectParts for FS.
Previously we had disabled ListMultipartUploads and ListObjectParts
to see if any clients break. Docker registry broke. This patch
enables ListMultipartUploads and ListObjectParts, however
ListMultipartUploads with prefix based listing is not
supported (which is not used by docker registry anyway).
i.e ListMultipartUploads will need exact object name.
