Refactor persistence JPA testing

Adding tests for EclipseLink and refactoring Hibernate testcases.

As both tests use the same test entities, the two existing test entity
classes from org.onap.policy.apex.plugins.persistence.jpa.hibernate
are moved to a newly created package
org.onap.policy.apex.context.test.entities under context-test-utils.

Relevent POM files are changed w.r.t this change. In particular,
 1) add version infos as properties in apex-pdp/pom.xml
 2) common dependencies related to Junit testing for EclipseLink and
Hibernate are moved to their parent plugins-persistence-jpa's POM.
