Handle timer expiration on state changes

Update to start all tach sensor functional state change timers on a fan
where the corresponding state and inventory is updated when the timer
expires.
Only start the timer in nonfunctional mode when a tach sensor is out of
range and is currently functional and start the functional mode timer
when its in range and currently nonfunctional.

Tested:
    Tach sensors are marked nonfunctional as normal.
    Tach sensors are updated to functional after 5sec(yaml test value)
    Nonfunctional timer is cancelled if fan returns within spec
    Functional timer is cancelled if fan returns out of spec
