currently we are testing what is needed to get consul + registrator and 
kolla/kolla-ansible play together nicely.

To get the services created in consul by registrator all kolla 
containers running relevant services (eg. keystone, nova, cinder, ... 
but also mariadb, memcached, es, ...) need to "--expose" their ports.
Registrator will use those "exposed" ports to add a service to consul.

I there any (existing) option to add those ports to the container bootstrap?
What about "docker_common_options"?

command should look like:

docker run -d --expose 5000/tcp --expose 35357/tcp --name=keystone ...
