Adds a module tripleo_service_vip which manages
a neutron API port resource for service virtuap IPs.
(redis and ovn_dbs) when neutron service is available.
When the service network is 'ctlplane' the module does
a find_port for the controlplane_virtual_ip so that the
ctlplane VIP is used in this case.
When the neutron service is not available the module
looks for a pre-defined ip address in the fixed_ips
option. If present this address is used, if not present
an exception is raised.
The module updates the 'service_vip_vars.yaml' file in
the playbook directory so that include_vars can be used
to load the variables.
The change also updates action/tripleo_all_nodes_data.py
and tripleo_hieradata templates to use the new variable
to source the service virtual IPs for redis and ovn_dbs
services.
