The strategy plugin previously did not support container detection
when the delegate_to host was a container. This adds support for
delegating tasks to other containers, so the strategy will perform
the same container vars lookups so the SSH connection is toward the
physical host of the container, and the command is wrapped with
lxc-attach based on the container_name.
