Problem: cannot restore transfer Bagit packages to start appraisal

[peterVG]

As per issue #391, backlog transfers will be stored in a Transfer Storage location in the Storage Service.

There is an existing CLI command to make backlog packages available to the pipeline from the backlog location: https://github.com/artefactual/archivematica/blob/stable/1.8.x/src/dashboard/src/main/management/commands/rebuild_transfer_backlog.py

With the new "transfer storage" implementation we need a new or upgraded command to restore transfer packages so that they are available to Backlog, Appraisal, and Ingest SIP creation features in the pipeline.

• [ ] Open Bagit package and move files to Appraisal working directory (/originals folder)
• [ ] Update ES index (for packages being restored from Transfer Storage)
• [ ] Insert data into MCP database

Your environment (version of Archivematica, OS version, etc)

Would this be a reasonable test plan for this issue:

• populate a backlog with packages
• delete the pipeline (maybe not necessary?)
• install a new pipeline and index the backlog from previously created transfers
• ensure transfers can be arranged into SIPs.

pinging @peterVG and @scollazo to give feedback on that

Above testing plan is correct - @scollazo, assigning to you!
