Add logging for Fan Presence / Redundancy

Add logging and fix bug with shared_ptr usage. We
now use a std::optional * to the shared redundancy
object, so that it can 1. point to object / null and 2.
exist in config or not.

Tested: cat /var/log/redfish to see logs made by removing
and adding fans, and using sensor override to change
redundancy.

dbus-sensors

dbus-sensors is a collection of sensor applications that provide the xyz.openbmc_project.Sensor collection of interfaces. They read sensor values from hwmon, d-bus, or direct driver access to provide readings. Some advance non-sensor features such as fan presence, pwm control, and automatic cpu detection (x86) are also supported.

key features

  • runtime re-configurable from d-bus (entity-manager or the like)

  • isolated: each sensor type is isolated into its own daemon, so a bug in one sensor is unlikely to affect another, and single sensor modifications are possible

  • async single-threaded: uses sdbusplus/asio bindings

  • multiple data inputs: hwmon, d-bus, direct driver access
