Create a human-readable list of deleted bags

[alexwlchan]

The "delete bag" script records the deletion in the deleted_bags table in DynamoDB, including a date, a reason, and the name of the person who deleted it. For example:

{
  "environment": "prod",
  "version": "v1",
  "events": [
    {
      "deleted_at": "2021-03-17T12:52:12.893877",
      "reason": "This is a bag that got sent to the testing space, which I meant to send to the born-digital space",
      "requested_by": "arn:aws:sts::760097843905:assumed-role/platform-superdev/chana@Wellcomecloud.onmicrosoft.com"
    }
  ],
  "ingest_id": "2c0f2583-4e64-4db9-b64b-f5952b411b18",
  "space": "testing",
  "externalIdentifier": "PPKIN/B/2/5/3"
}

It would be useful if this data was available in a more human-readable form, similar to the list of Miro image suppressions. This list should live in a private repo, similar to the list of Miro suppressions.

• Modify the script to delete bags (ss_delete_bag.py) to maintain this table
• Add a link to this table from the GitBook documentation about deleting bags
