CERN reported two issues with archive_deleted_rows CLI:
* When one record gets inserted into the shadow_instance_extra but 
didn't get deleted from instance_extra (I know this is in a single 
transaction but sometimes it happens), needs manual cleanup on the 
* Also there could be two cells running this command at the same time 
fighting for the API db lock,

* tssurya to report bugs / improvements on archive_deleted_rows CLI 
based on CERN's experience with long table locking
* mnaser to report a wishlist bug / specless bp about one step db purge 
CLI which would skip the shadow tables
