Initial version of ResourceAdaptationProcessor and friends.

This CL adds Resource, ResourceConsumer, ResourceConsumerConfiguration
and ResourceAdaptationProcessor and implements the algorithm outlined
in
https://docs.google.com/presentation/d/13jyqCWNpIa873iKT6yDuB5Q5ma-c0CvxBpX--0tCclY/edit?usp=sharing.

Simply put, if any resource (such as "CPU") is overusing, the most
expensive consumer (e.g. encoded stream) is adapted one step down.
If all resources are underusing, the least expensive consumer is
adapted one step up.

The current resources, consumers and configurations are all fakes;
this CL has no effect on the current adaptation algorithms used in
practise, but it lays down the foundation for future work in this
area.
