Add modes to phosphor-fan-control

phosphor-fan-control can behave differently based
on its command line arguments

--init:  Set fans to full speed, delay for a
         configurable amount of time to allow fans to ramp up,
         start the fan control ready target, and then exit.

--control:  Start the control algorithm.  Never exits.
            Will be started as part of the fan control ready target.
