merge: Prepare for risk analysis experiments

This pull request adds the necessary code in preparation for the  risk analysis experiments:

- Track provisioning time
- Track host up/down time
- Track guest up/down time
- Support overcommitted memory
- Do not fail inactive guests
- Mark unschedulable server as terminated
- Make ExperimentMonitor optional for trace processing
- Report up/downtime metrics in experiment monitor
- Move metric collection outside Capelin code 
- Resolve kotlin-reflect incompatibility
- Restructure input reading classes

**Breaking API Changes**
- `ExperimentMonitor` replaced in favour of `ComputeMonitor`
