Goal: 

• A user should be able to delete or bulk delete snapshots
• DELETE /content-sources/api/v1/repositories/<uuid>/snapshots/<uuid>
• POST /content-sources/api/v1/repositories/<uuid>/snapshots/bulk_delete/
  • body: { uuids: [] }
• Deleting a snapshot should also delete the repository version, publication, and distribution in pulp. This would need a new task. Task should delete one or multiple snapshots.
• Want to soft delete the snapshot so the task can still use it.
• Update a template to next snapshot before deleting

Acceptance Criteria:

• Delete and bulk delete endpoints are implemented as described.
• Deleting a snapshot spawns a task that also deletes pulp objects.
• A user should not be able to delete the last snapshot in a repository.
• Errors should be returned in a list, similar to the repository bulk delete endpoint
