Add support for processing start event triggers

Process application start event triggers' list of conditions on a group
and perform the defined actions.

This re-uses the following structs(and their necessary functions)
directly from phosphor-inventory-manager:
--struct PropertyConditionBase
--struct PropertyCondition
