SO poll should not require request ID
When SO is polled for the result of a previous request, it does not necessarily include the originally returned request ID in the response. This causes the SO actor to generate a "missing request ID in response" exception. Modified the actor to only extract the request ID from the first response and cache it for subsequeent responses. Testing this required the SO simulator to be modified so that it would return an INCOMPLETE on the initial request, forcing the actor to poll until it returns a COMPLETE. Made this a settable flag so that it could be enabled just to test the SO actor without impacting other components (e.g., drools-apps, CSITs). Also fixed a couple of checkstyle issues in the simulators. Issue-ID: POLICY-2568 Change-Id: Ifad8b3c0c2c0b03cb82da693c2cf5ced44ede105 Signed-off-by: Jim Hahn <jrh3@att.com>
