Spec Lite: Add glance-cache-manage utility using v2 API

project

glance

problem

In Rocky, the v1 dependant glance-cache-manage command was removed while removing Images API v1 entry points. As a part of Edge computing glance cache needs to be enabled on far-edge nodes via Split Control plane where glance-cache-manage utility will be essential to queue image for prefetching, to list & delete images from Image Cache.

solution

In Stein, as per Edge computing architecture, glance cache will be enabled on far-edge nodes. Hence it will be good to add glance-cache-manage utility using v2 API in glance. This utility will have the following commands and the same interface as Queens glance-cache-manage utility [0] insofar as possible, [0] https://docs.openstack.org/glance/queens/cli/glancecachemanage.html :

1. Queue the image with identifier <IMAGE_ID> for caching,

   $ glance-cache-manage --host=<HOST> queue-image <IMAGE_ID>

2. List all images currently cached

   $ glance-cache-manage --host=<HOST> list-cached

3. List all images currently queued for caching.

   $ glance-cache-manage --host=<HOST> list-queued

4. Delete an image from the cache

   $ glance-cache-manage --host=<HOST> delete-cached-image <IMAGE_ID>

5. Remove all images from the cache

   $ glance-cache-manage --host=<HOST> delete-all-cached-images

6. Deletes an queued image from the cache

   $ glance-cache-manage --host=<HOST> delete-queued-image <IMAGE_ID>

7. Remove all images from the cache queue

   $ glance-cache-manage --host=<HOST> delete-all-queued-images
