    Restore swift storage directory permissions after upgrade

    Any update or reinstall glance-common package triggers
    its postinst action with following command:
    chown glance:glance -R /var/lib/glance/ /etc/glance/
    We use /var/lib/glance/node by default as swift storage
    folder http://goo.gl/97VJG2, and reinstallation of
    glance-common breaks swift user access to it, so swift
    services stop working. So, we need to fix /var/lib/glance/node
    folder permissions right after upgrade command.
    Also, the case of adding new controller node for already
    updated cluster is covered.
    This workaround is applied on when swift is enabled.
