Related to #176 (closed), audit-control-environment#80, audit-control-environment#81, audit-control-environment#82, https://ucsdlibrary.atlassian.net/browse/TDX-599

What are this MR suggest to do?

Automate the process of collection deletion process:

• Add new REMOVED status for replications to flag REMOVED collections on ACE.
• Setup cron job to run periodically.
• Check for REMOVED state collections on ACE.
• Retrieve all replications that a collection has and update its status to be REMOVED if files were deleted already.
• Update the collection's status to be DELETED if all replications have REMOVED status.

Screenshots:

• Output from the cron job to check for removed collections on ace and update the collection status once criteria is meet.
• Replication with REMOVED status updated.
• Collection that is updated to be deleted by the process.
