Create fan monitor init mode

Allowing fan monitor to run in an init mode will set the fans to a
functional state at each poweron for fans that were non-functional at
poweroff. Then fan monitor can be started in monitor mode after the fans
have ramped up to full speed and can begin being monitored for faults.

This also allows for the removal of fan monitor doing a sd_notify prior
to fan control starting.
