merge: Address technical debt in codebase

This pull request removes some of the existing technical debt in the OpenDC codebase.

Close #51

## Implementation Notes :hammer_and_pick:

* Add Pacer to pace scheduling cycles.
* Rename utils module to common module
* Optimize TimerScheduler
* Remove opendc-platform module
* Disallow duplicate UIDs for SimHost

## Breaking API Changes :warning:

* TimerScheduler does not implement `AutoCloseable` anymore.
