Moving the network and port management for OVN
bridge MAC addresses to ansible.
Removes the heat resources, and adds an external
deploy task at step 0 in the ovn controller service
templates which uses the 'tripleo_ovn_mac_addresses'
ansible module to create/remove OVN mac address ports.
Adds parameter role_specific OVNStaticBridgeMacMappings,
parameter that can be used to set static bridge mac
mappings. When this is set no neutron resources will be
created by the tripleo_ovn_mac_addresses ansible module.
OVNStaticBridgeMacMappings must be used for standalone
deployments.
