Sensor alarm logging in IPMI SEL

[Lei YU]

The existing phosphor-dbus-monitor should be able to do that.
It requires a yaml config to define the watches and actions.

See [witherspoon example][1], that watches the properties (ThrottleProcTemp,
ThrottleProcPower, ThrottleMemTemp) on /org/open_power/control/occ0, and log
the related events.
