Subject: vendor patched upstream docker_container module.
Due to the use of a restricted name in the core `docker_container`
module's result, any standard output of a docker container captured
in the module's response was stripped out by ansible.
Because of this, we are forced to vendor a patched version of this
module, until a new version of ansible is released containing the
patched module.
This file should be removed once we begin requiring a release of ansible
containing the patched `docker_container` module.
This patch was taken directly from upstream, with no further changes:
