feat: creating neutron objects in openstack using ansible

[haseebsyed12]

1. openstack network segment ranges (check existing) and one segment range (just one for the whole fabric) for vxlan type segments
2. subnet pool for the OUTSIDE networks.
3. Baremetal nodes and their baremetal ports in ironic for the three "infra" nodes.
4. Each of the nodes needs neutron ports, (trunks with sub-ports where required) associated with the appropriate networks.

configurations are in undercloud-deloy repo
output log for playbook openstack_network.yml
output log for playbook openstack_baremetal.yml

Does this need to be different playbooks for neutron/ironic? Is that a technical limitation in ansible?

It seems like we would want all of this or none of this, I can't see a scenario where we would want to populate ironic but not neutron.
