Show Delete replication status header (#10946)

X-Minio-Replication-Delete-Status header shows the
status of the replication of a permanent delete of a version.

All GETs are disallowed and return 405 on this object version.
In the case of replicating delete markers.

X-Minio-Replication-DeleteMarker-Status shows the status 
of replication, and would similarly return 405.

Additionally, this PR adds reporting of delete marker event completion
and updates documentation
