Description Richard Barrott 2020-04-07 23:31:46 UTC 
Description of problem:
By default, SNAT is distributed on all of the nodes instead of just the Network nodes.  
Per: https://opendev.org/openstack/tripleo-heat-templates/src/branch/stable/queens/environments/neutron-ovs-dvr.yaml#L28


Version-Release number of selected component (if applicable):

Additional info:
Customer requests that with the use of composable roles,the default should be a little more dynamic; for example any role running certain compute related services (like nova_libvirt) would get NeutronL3AgentMode: 'dvr' if not specified, rather than hard coding to just a single role (that we expect very few site actually use in production, due to running different physical servers)
