kolla-kubernetes resource magic

The kolla-kubernetes resource command does multiple cli commands per resource command. This seems to be better done at a workflow level as not every resource_name should always be instantiated. Instead I propose we change kolla-kubernetes resource to be a simple mapping from resource to kubectl + resource-teplate. so for example:

kolla-kubernetes resource create pod nova-api
#becomes shorthand for:
kubectl create -f <(kolla-kubernetes resource-template create pod nova-api)

It would only operate on resource_names and not services.
