Turn the rll_tools package into a python package.

* now you are able to import `run_project` e.g. for tests and you can call `run_project_in_background` in your client code to avoid having to trigger the project execution manually
* the submit part has been refactored a bit to make it easier to reuse, e.g. for the rll_server
* future proofing fix: use `filter` instead of `exclude` in `tar.add` to be compatible with Python3

Note: the python2-typing package does not appear to be installed in the CI docker images, therefore I adjusted the CI config to install it
