Remove networks from Undercloud and Standalone roles

Change https://review.openstack.org/614457 added these
networks because of the defaults in ServiceNetMap. With
changes related to LP Bug #1809313 these are no longer
required, as the ServiceNetMap fall's back to ctlplane
when networks are not defined or disabled in networks
data.
