The incorporation of swagger into source code base for the "/test" interface is faulty:
1.  eclipse shows project errors associated with plugin usage.
2.  the actual documentation for the "/test" server within policy-persistence does not produce API documentation. 
3.   only covers swagger spec for "/test".

4. it generates a swagger spec under drools-pdp/target and not packaged in any way.

The changes here correct the previous defects, and makes the solution generic for any API supporting in the PDP-D.
