* Fix ansible-test docker container detection. * Attach test containers to the correct network. * Do not assume `localhost` for accesing Docker. * Look for containers on current network. * Always map /var/run/docker.sock into containers. This fixes issues when using a remote Docker host. * Support container IP lookup from networks list. * Fix container network attachment. * Remove redundant container detection messages. * Limit DOCKER_HOST parsing to TCP. * Restore docker socket existence check. The check is skipped if the docker hostname is not localhost. * Correct changelog entry.. (cherry picked from commit3c2e8b99be) Co-authored-by: Matt Clay <mclay@redhat.com>.
