simulator: Add energy modelling subsystem to OpenDC

This pull request adds a subsystem to OpenDC for modelling power components in datacenters,
such as UPSes, PDUs and PSUs.
These components also take into account electrical losses that occur in real-world scenarios.

- Add module for datacenter power components (UPS, PDU)
- Integrate power subsystem with compute subsystem (PSU)
- Model power loss in power components

**Breaking API Changes**

1. `SimBareMetalMachine.powerDraw` is replaced by `SimBareMetalMachine.psu.powerDraw`
