Feature: Passing host vars to container host?

[rlanyi]

It would be nice to pass along every variable that were defined in group_vars and host_vars and in the inventory file to the host created with add_host. This way all existing playbooks could be run against the container without change.

There are comments about this in tasks/inc_inventory_iface.yml and tasks/inc_cloud_iface.yml:

    # TODO: copy ALL host vars in the inventory

Any suggestions on how to do this properly?
