harness: Improve OpenDC Experiment Harness (v1)

This pull request contains several improvements to the OpenDC Experiment Harness, 
which aims to improve user-experience of users when re-running experiments in the repository.

*  Split the harness into separate modules
*  Add support for adding additional classpath entries when running experiments via the console
*  Initial support for configuration of experiments using HOCON.
