[POLICY-105] Modifications to RefreshStateAudit

Made the refreshStateAudit configurable and changed the default interval to 10 minutes from 1 minute.  Added a check to fpCheck to check the state of the dependent before setting the opstate to disabled.

Added a refresh to the forwardprogressentity object in stateAudit() so that we are not reading stale timestamp data.
