[ECOMPD2TD-000] Update version.properties for iter 41 [US866186 1707] Adding methods to IntegrityMonitor to support state audit. [US866186 1710] Made more progress on teh stateAudit method of IntegritryMontor. Completed all except the addition of properties. [US866186 1710] Addition of IntegrityMonitorProperties.STATE_AUDIT_INTERVAL_MS and logic to stateAudit to determine whether or not to run [US866186 1710] Created a JUnit for getAllForwardProgressEntity() method and debugged and fixed it. [US866186 1710] Making progress on the testStateAudit() JUnit. Was able to create forward progress entries and manually change the lastUpdated date on an entry using a persistence update query. [US866186 1710] First cut of stateAudit JUnit test. Still need to test more cases, but I got it working so far. [US866186 1710] Completed the JUnit for stateAudit. Added 5 new scenarios.
