I would be nice if we could rename a container (and/or remove the container name)

The problem I face today is that I might depend on container naming to determine if a container is already running, or otherwise present on a system. But If I have to remove the actual container to remove the name I risk destroying data.

I'd suggest just naming the command 'rename' or just 'name'

Removing the container name could be docker name <containerid> ""
