CoS:

• Create WaitForPnfReadyBB based on current implementation from CreateAndActivatePnfResource.bpmn 
• CreateAndActivatePnfResource.bpmn should not be deleted and should remain working
  • We need to ensure that Java code used by CreateAndActivatePnfResource.bpmn is compatible with both legacy and GR/BB implementation
• Building block should raise an error when entry in AAI does not exist

Demo scenario:

• Run demo flow containing WaitForPnfReadyBB from SO API (on some demo service model)
• Show in SO Monitoring that flow stops and waits for PNF ready event
• Send PNF ready event to DMaaP
• Show in SO Monitoring that flow ends without errors
