    doc: fix resize user guide link

    The admin config resize doc was linking to a now non-existent
    user guide doc which was deleted in pike. This change imports
    the resize user guide from the openstack-manuals stable/ocata
    branch, fixes the link, and updates the resize user doc to
    (1) link to our internal shutdown_timeout config option reference
    and (2) link to the image properties doc in glance for the
    os_shutdown_timeout image property.
