    Do not use service catalog for cache client
    
    Previously cache client used endpoints from service catalog to
    request cache items from node. It works perfectly on devstack
    but it doesn't work when an OpenStack cloud is deployed with HA
    (3/5/7 controllers). We need to use -H option instead.
    This option makes cache management client interact with the local
    endpoint which is more appropriate as image cache is local to
    each node/controller.

Title:
  glance-cache-manage talks to image endpoint instead of the specified
  host

Status in Glance:
  Fix Released
Status in Glance newton series:
  New

Bug description:
  Corrected bug description (based on the comments below):
  In Glance, image cache is local to each node. And, hence, image cache management must be performed on each node locally. This is supported by providing a specific host using '-H' or '--host' argument to glance-cache-manage utility.

  However, due to a bug glance-cache-manage currently ignores the
  provided host and fetches the image endpoint to manage the cache.
  While this does manage the cache, we don't know what node is being
  managed here. This can be fixed by passing 'configure_via_auth=False'
  when creating the image cache client. This ensures that image endpoint
  is not fetched and the provided host is used.

  Initial bug description:
  If we want glance-cache-manage commands to communicate over internalURL, it doesn't support. It always use publicURL for communication.
