Description of problem:

We need to add to the docs instruction on how to deploy overcloud with vlan tenant network when using network isolation.

I got a successful deployment by using the following but we need some more details on how to do this based on the supported network configurations:

openstack overcloud deploy --plan-uuid c2a99e75-f9b7-49c4-bbdc-a658a52ef766 --control-scale 3 --compute-scale 1 --ceph-storage-scale 0 --block-storage-scale 0 --swift-storage-scale 0 -e /home/stack/network-environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml --network-cidr 10.19.95.0/24 --neutron-bridge-mappings datacentre:br-ex,vlan:br-vlan --neutron-network-vlan-ranges vlan:183:185 --neutron-network-type vlan --neutron-disable-tunneling
