Adds a Hardware class with hooks for entering and exiting "benchmarking" mode (e.g. locking clocks, etc.) as well as periodic polling of hardware to verify the environment is stable. Adds a partial implementation for generic Android hardware, but ultimately we will need to write specific classes tailored to each unique platform we need to test.
