Description of problem:
When trying to delete a cluster with image-registry swift container full of objects, those objects are being deleted one by one, making the process slow.

We need to explore how to remove containers without needing to delete each object on it, as this process makes deletion process.

How reproducible:


Steps to Reproduce:
1.Add objects to the image-registry included on the OCP installation
2.Trigger cluster deletion
3.Watch installer log to track deletion of each object on the container

Actual results:
Process takes more time or less depending on the number of objects in the container

Expected results:
Container is full deleted no matters how many objects it contains
