Remove Rendundant info from cli commands

We currently put a lot of redundant information into various places making it hard for operators to use. For example:
kolla-kubernetes resource-template create nova pod nova-api-pod

Nova's in there twice, as is pod. This extra level of detail doesn't actually have any benefit I can see. we should rename our resources and rework the cli args so the redundancy is removed:
kolla-kubernetes resource-template create pod nova-api
