[jboss-as7-dev] Starting to fork EJV3 JPA tests into testsuite/integration...

I'm taking an early stab at hacking some JPA tests together. They don't work yet but will be a work in progress as we decide how to do such testing. I started with https://github.com/scottmarlow/jboss-as/tree/master/testsuite/integration... which should merge into as7 master (upstream) soon. Feedback on the epcpropagation test is welcome. :-) Scott
