+Ansible module for determining information about the docker host.

+While there are several ansible modules that make use of the docker
+api to expose container and image facts in a remote host, they
+are unable to return specific information about the host machine
+itself. This module exposes the same information obtained through
+executing the `docker info` command on a docker host, in json format.
