Add AutoClose wrappers for JPA classes
Added EntityMgrCloser and EntityMgrTrans classes that will automatically close/rollback the wrapped JPA classes. As a result, these classes can be used in try-with-resource statements to ensure that the JPA EntityTransaction is rolled back and the EntityManager is closed. Add "build" section into pom to make it consistent with other poms in common. Changed scope to "provided" in utils pom for javax.persistence to prevent clashes with other projects that depend on the utils project. Changed scope to "test" in utils pom and to "provided" in utils-test pom for junit. Fixed license date in EntityTransCloser. Fixed license titles in utils & utils-test source files. Moved files from package xxx.test.jpa to package xxx.jpa, because they are not test-specific classes. Include exception when logging message in ThrowablesTester, hopefully eliminating sonar complaint.
