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.
