simulator: Add uniform resource consumption model (v2)

This is the second pull request in the series of pull requests to add a uniform resource consumption model to OpenDC. This pull request focusses on adding dynamic capacity negotiation and propagation between resource consumer and resource provider:

* The generic resource constraint is removed from the interfaces of `opendc-simulator-resources`. Users of the API are expected to use the untyped variants where only the capacity needs to be specified. Users are expected to build higher-level abstractions on top of these interface to represent actual resources (e.g., CPU, disk or network).
* Added benchmarks for the most important implementations of `opendc-simulator-resources`. This allows us to quantify the effects of changes on the runtime.
* The `SimResourceSwitchMaxMin` has been split into a `SimResourceAggregatorMaxMin` and `SimResourceDistributorMaxMin` which respectively aggregate input resources and distribute output resources using max-min fair sharing.
* The `SimResourceConsumer` interface has a new method for receiving capacity change events: `onCapacityChanged(ctx, isThrottled)`

**Breaking API Changes**

*  All interfaces in `opendc-simulator-resources`.
