SWITCHYARD-2456 improve integration test coverage for eap/wildfly distros

https://issues.jboss.org/browse/SWITCHYARD-2456

Note, the jboss.home property is now eap.home for eap builds and wildfly.home for wildfly builds.  This was changed because jboss.home is used by some of the updated unit tests and cannot be overridden by surefire if it is specified on the command line using -D.  I think there are still intermittent test failures with CXF quickstart test.
