Update CI tests to run python docker library against API

* Update reference to docker-py to docker to reflect change in library
  name
* Update tests to create storage sandbox
* Enable all tests that endpoints support
* Refactor containers/{id}/rename to return 404 not 500
* Refactor tests to use quay.io vs. docker.io
