    Bind mount /var/lib/iscsi in containers using iSCSI

    Services that create iSCSI connections need to share the connection info
    that gets created in /var/lib/iscsi. It's especially important that the
    host has knowledge of *all* connections so that it can disconnect them
    whenever the host shuts down or reboots.

    Note: Minor changes were included in the backport to stable/rocky.
    - The ":z" propagation suffix added to the volume mounts in stein were
      omitted.
    - In stein the glance-api service templates were moved to the unified
      deployment/glance-api directory, so the rocky changes are made in the
      original docker/services directory.
