presence: Add new tach sensor implementation

Add a new fan speed (tach) presence implementation for the new
PresenceSensor interface.

This fan tach sensor behaves mostly like the existing one, with
the addition of support for multiple tach sensors for the
single PresenceSensor instance, and implementation of the
PresenceSensor start and stop interfaces.

presence: Add redundancy policy interface

Add a redundancy policy interface class. Redundancy policies
introduce the concept of multiple presence sensors for a given
fan. A redundancy model implementation determines how the
distinct sensors making up the redundancy set are controlled
and how their feedbacks determine the overall fan presence state
reflected in the inventory.

Switch which GPIO value sets air or water cooled

During the coding and testing of this application there was some
miscommunication on the jumper position for a Witherspoon system. The
system was jumpered for Air when intended to be jumpered for the Water
cooled position. Further examination of the documentation and the jumper
settings on systems found that the logic was reversed. This change
should correct the problem and report the correct cooling properties.

Add increase & decrease timer values in seconds

Support setting the increase delay time(in seconds) for each zone from
the zone yaml file. Speed increases use a delay type timer where the
amount of time given delays additional increase requests from happening
until the fans within the zone reach the highest net increase in speeds.

Support setting the decrease interval time(in seconds) for each zone
from the zone yaml file. Since decreasing is done on an interval, a
decrease interval time of zero disables the decrease interval timer
causing no decreases in speed to occur. Speed decreases use an interval
type timer to decrease the fan speeds within the zone when no speed
increase requests exist on the given time interval.
