Rename heat-kubernetes, heat-mesos, docker-swarm

Rename heat-kubernetes to kubernetes, heat-mesos to mesos,
docker-swarm to swarm in templates.  We use heat templates and
no other methods, so I think it is unnecessary to add heat before
coe. kubernetes, mesos, swarm are better than
heat-kubernetes, heat-mesos, docker-swarm.
