Description
Currently there is a comment in the docker-compose file that indicates that the test directory can't be mounted due to compiled Python version mismatches. This pull request removes this limitation. This is achieved by cleaning up pyc files in the docker entrypoint script which avoids mismatches between compiled Python files on the docker host and/or from previous build steps by construction: before executing any command in the docker container, any remnant platform specific files are cleaned up and as such any subsequent py.test command will run in a clean environment.
