improvements to audit inventory feature

Adjust test data to add tenant mapping
Remove unused unit test already renamed
Update logic, to pass hostname not pservername
remove unused file that has been refactored
Add project to ignore, remove class
Address issues in comments on pull request
Remove logging that is not needed, used
UPdate BPMN to use Boolean Value, change timings
Adjust BPMN to not hit deadlock scenario
put error message in execution before checking rollback
- removed extra code for vnf resource processing found in onap
environment.
Fix improper use of inclusive gateway causing deadlock
Fix flakey unit tests from ONAP
Remove qualifier on bean, as it breaks callbacks
Adjust pom version of external camunda client
Fix polling timers to be more reasonable
Updated Junit test for delete vf module in onap.
Changed auditInventoryNeeded variable to a boolean to prevent
bpmn from erroring out in the event this variable is not found
on the execution.
Update logic to support writing of self link
