IMO, coe is a little confusing. It is a term used by people related somehow
to the magnum community. When I describe to users how to use magnum,
I spent a few moments explaining what we call coe.
I prefer one of the following:
* openstack magnum cluster create|delete|...
* openstack mcluster create|delete|...
* both the above
It is very intuitive for users because, they will be using an openstack
and they will be wanting to use the magnum service. So, it only make sense
to type openstack magnum cluster or mcluster which is shorter.

"Magnum uses Heat to orchestrate an OS image which contains Docker

metal in a *cluster* configuration."
Many services may offer clusters indirectly. Clusters is NOT magnum's focus,
but we can't refer to a collection of virtual machines or physical servers
another name. Bay proven to be confusing to users. I don't think that magnum
should reserve the cluster noun, even if it was available.
