allow the usage of an external dockerhost provided the docker API is accessible

[tommyjcarpenter]

Is there a way to use this plugin with an external Dockerhost? By external, I mean a host that has Docker on it and the docker API exposed, but not under the management of Cloudify (meaning no SSH and no user-agent). Something like:

[docker node]
relationships:
- type: cloudify.relationships.contained_in
target: external_dockerhost

external_dockerhost:
ip: [some machine where docker is exposed but no SSH)
