fru-fault-monitor: Enable OperationalStatus monitor feature

Currently, the phosphor-fru-fault-monitor updates the Asserted
property of the Led Group D-Bus object by monitoring the
`/xyz/openbmc_project/logging` object path.

The intent behind this commit is to add another way to monitor the
`xyz.openbmc_project.State.Decorator.OperationalStatus` interface
of the Inventory D-Bus object, and check whether the Inventory
D-Bus object is associated with the LED group D-Bus object, and
then update the Asserted property of the LedManager.

Since both these methods handle the faults differently,
Only ONE of these 2 methods can be enabled and NOT both.

The first way is supported by default. To turn OFF the default way
AND turn ON this second way, Enable monitor-operational-status.
