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.
