[RHOSP17] Glance Image List/Save Fails or Slow due to connection to Ceph backend

Issue

• Glance CLI commands such as openstack image list or openstack image save are extremely slow (taking 4–5 minutes) or fail to complete when downloading or listing large images stored in the Ceph storage cluster.
• The command fails with one of the following error tracebacks:
  requests.exceptions.ChunkedEncodingError: ("Connection broken: ConnectionResetError(104, 'Connection reset by peer')", ConnectionResetError(104, 'Connection reset by peer'))
  or
