support new query param format

- added format query parameter (optional), implemented logic to
populate requestStatus field based on whether or not format is present
moved request status constants to its own class visible globally.
- changed @requestParam to @QueryParam in GET endpoint
(OrchestrationRequests class. updated unit tests to call method being
tested directly rather than from another private function
- moved setting requestStatus to a separate method, also updated unit
tests to separate out each scenarion into its own method
- added unit test for when format=detail, corrected existing unit tests
to test result to be FAILED
- updated Status.java to include extra request status values; moved
Status class to common org.onap.so.constants package
