Starting LMS and Studio with manage.py

Despite the environment variable overrides, Paver still seems to be  doing more than is necessary to start LMS and Studio. Skip Paver, and run the server directly via Django's manage.py, like every other service.

Additionally, the removal of old Python libraries has been disabled when installing prerequisites. This is not necessary for Docker images, and removing packages causes Django to stop and the container to shut down.
