* [pidcontroller] Implement previous state recovery on startup
This feature allows the PID controller parameters to be updated and
OpenHAB to be restarted without losing the current controller state.
This is especially important for systems with a long response time.
For example it might take up to a day for an underfloor heating
controller to stabilise after losing state and having to build up
the integrator value from zero.
