Review the way testsuite is run using Maven

Instead of requiring us/users to do what follows to run the testsuite

> mvn -Ptestsuite,jbossXYZ -DjbossXYZ.home=.. test

we should probably be able to support something like:

> mvn -DjbossXYZ.home=.. integration-test

The move of non-unit tests to integration-test phase is being done as part of JBWS-3210, the rest is probably a matter of implicitly getting the target container from the jbossXYZ.home defined in the env and removing the testsuite profile / automatically enabling the testsuite modules, which just have integration tests.
