Make docker.yaml default environment file

[Janki Chhatbar]

prepare command prepares a list of docker images for services enabled.

openstack overcloud container image prepare --namespace tripleoupstream --tag latest --env-file ~/docker_registry.yaml -e /usr/share/triple-common/environments/services-docker/neutron-opendaylight.yaml

produces just ODL related images.

Add docker.yaml as default service-environment-file so that above commands produces images for all supported services + ODL. Adding too many env files is confusing to users.

We spoke about making docker.yaml our upstream default in Queens at the recent PTG. Pending feedback on the mailing list I think we plan on proceeding with this soon.

The solution we use needs to work for but the UI and CLI. I think this means we should wire it in via a hook to the Mistral workflow that drives deployment.

I've actually got a patch that implements this downstream for Red Hat which I was planning on re-working for Queens.

Dan, I was unaware of such discussion. I already have a patch in review (https://review.openstack.org/507349). Feel free to edit/rework on this.

This proposes to make docker.yaml default for "prepare" command. Bug 1701532 proposes to make it default for "deploy" command.
