Only include defined trust determination sensors in checking the group
trust.
Tested:
Current trust group associations & reactions are unchanged

To simplify sensor and trust access, utilize a struct in place of a
tuple for storing the trust group sensors and their inclusion in the
trust determination.
Tested: Current trust group associations & reactions are unchanged

Each sensor listed to be associated with a trust group is defined to
either be part of the trust group or just affected by the results of the
trust group. This is denoted by defining an "in_trust" boolean attribute
that will include the sensor in the trust group for determination of
trust when true, otherwise only be included in the resulting trust
affect when defined as false.
When no "in_trust" attribute is given, the sensor is defaulted to be
included in the trust group determining trust.
Tested: Current trust group associations & reactions are unchanged

The fan and trust group objects should utilize shared pointers to the
tach sensor objects. This allows optimizing the storage of additional
attributes associated with the tach sensors.
e.g. An attribute to declare which sensors should be included in the
trust determination.

This class provides the ability to only trust
the sensors in the group if at least one of them
has a nonzero speed.
It is being used for a system where the tach values for
a set of rotors are reported as zero by the fan controller
hardware when the other rotor on the fan is moving to a
new target speed. As all the fans are set to the same speed
at the same time, the rotors in question all report as
zeros at exactly the same time, and this is then used to
know when the values cannot be trusted.
