Public bug reported:

1.Set delayed_delete is true in glance-api.conf

2.Create an image by URL, then delete the image.
Because of delayed_delete is true, the image is in pending delete state in the database.

3.Using the glance scrubber to clear image records, the script log reports error such as:
2025-01-23 20:17:48.191 484 INFO glance.scrubber [-] Scrubbing image 76ab1055-xxxx-xxxx-xxxx-xxxxxxxxxxxx from 1 locations.
2025-01-23 20:17:48.192 484 ERROR glance.scrubber [-] Unable to scrub image 76ab1055-xxxx-xxxx-xxxx-xxxxxxxxxxxx from a location. Reason: Deleting images from this store is not supported. : glance_store.exceptions.StoreDeleteNotSupported: Deleting images from this store is not supported.

I noticed that in glance_store/capabilities.py, op_cap_map states that delete requires WRITE_ACCESS permission.
And in glance_store/_drivers/http.py, the _CAPABILITIES is (capabilities.BitMasks.READ_ACCESS | capabilities.BitMasks.DRIVER_REUSABLE)

Unfortunately, I haven't found any documentation on why HTTP deletion
operations are not allowed yet.
