Fix python dockerpy tests

* Refactor packaging so unittest discovery works
* Refactor tests to use python3-docker.rpm that ships with Fedora32
* Flush image cache between tests suites
* Update documentation to reflect changes

Outstanding issue:
* client.get_image() does not fail if image does not exist
