AT:

• determine whether delete endpoint is required. If so, implement it.

Testing notes:

• See https://confluence.camunda.com/display/CO/Backup for setup
• delete an existing backup should return 204, use either backup state or ES API after delete to ensure backup was removed
• delete a nonexistent backup should also not cause an error
• deleting a backup where some snapshots are already deleted should also not cause an error
• deleting a backup when the respository does not exist should cause an error response
• delete endpoind only deletes the snapshots associated with the given ID
• Details see confluence backup section or google API docs linked in comments
• API is documented on confluence (user docs to follow in separate docs ticket)
