Add uniform resource consumption model (v1)

This is the first in the series of pull requests to add a uniform resource consumption model to OpenDC. This pull request introduces the `opendc-simulator-resources` module which introduces the primitives with which we can model resource consumption of CPUs, disks and network:

* `SimResourceProvider` represents a provider of some generic resource `R`, which may be consumed via `consume(SimResourceConsumer<R>)`
* `SimResourceConsumer` represents a resource consumers and characterizes how the resource is being consumed.
* `SimResourceSwitch` is a generic scheduler for sharing the capacity of multiple resources across multiple consumers.
   - `SimResourceSwitchExclusive`: A space-shared switch - each consumer is allocated a single resource exclusively.
   - `SimResourceSwitchMinMax`: A time-shared switch - each consumer gets a fair share of the resource capacity. 
* `SimResourceForwarder` converts a consumer in a provider.

**Breaking Changes**
* `ProcessingUnit` and `MemoryUnit` renamed to `SimProcessingUnit` and `SimMemoryUnit` respectively.
* `TimerScheduler` accepts a `CoroutineContext` as opposed to a `CoroutineScope`.
