exp: Add experiment for OpenDC Energy project

This pull requests adds an experiment to the repository for the OpenDC Energy project. 
This experiment currently runs the Solvinity traces and tests how different energy 
models perform.

* Add new experiment `opendc-experiments-energy21`
* Link experiment to `ConsoleRunner` so that the experiment can be run from the 
   command line.
* `BatchRecorder` is now used to emit all metrics at once after the hypervisor 
    finishes a slice.
