    Remove use of keepalived 'vrrp_sync_group' as it is unused

    Now keepalived configuration wraps the VRRP instances with a
    'vrrp_sync_group'. The VRRP sync group functionality is only
    relevant when more then one VR instance is contained in it.
    In that case the VRs in the group will have the same state.
    Our use of keepalived uses a single instance per router.

    This patch simply removes the 'vrrp_sync_group'.
    In this patch VR instances are used on their own and they now
    hold the 'notify_scripts'.

    Note that the same VRRP functionality is preserved with this
    patch.

    Another motiviation for this patch, aside from removing
    useless configuration, is to lay the foundation for a future
    patch that will the related bug by adding 'track_script'
    that are not supported with 'vrrp_sync_group'.
