Upgrade to Docker 1.12

[chouseknecht]

Tracking progress on completing the upgrade to Docker 1.12 and hopefully adding support of Docker for Mac

[chouseknecht]

• files in container/templates have been updated to install docker-latest rpm, docker-compose 1.8.1, and docker-py 1.10.3
• .travis.yml no longer downgrades Docker to 1.11.2
• updated ansible/ansible-container-testing image

[chouseknecht]

Running into this issue: docker/for-mac#865

• upgraded Docker for Mac to 1.12.3-beta30.1(13946)
• Tests pass
• However, this error appears without interrupting anything:

test_1               | test/integration/test_slow.py::test_restart_minimal_docker_container PASSED

Looks like I'm seeing this issue: docker/compose#4090

[chouseknecht]

Testing with docker-py 1.10.6, docker-compose 1.9.0 and Docker for Mac 1.12.3-beta30.1

Still hitting docker/compose#4090

• appears to be related to restarting a stopped project.
• only happens when running tests using python 2.7.12
• tests pass despite the error
