Factor out container specific testsuite dependencies to ASIL / jboss-as-webservices-tests-integration

The stack testsuites use 'jbossXYZ' profiles for setting up the client dependencies. We currently have a lot of dependencies listed there which should be moved to container specific modules. In particular, for the latest AS snapshots, the dependencies need to come from the org.jboss.as:jboss-as-webservices-tests-integration artifact, while for released containers, the dependencies should come the corresponding ASIL.
Ideally, once this is done, the jbossXYZ profiles should list only the dependency on the ASIL / org.jboss.as:jboss-as-webservices-tests-integration artifacts. This btw allows for automatically keeping the client testsuite dependencies in synch with the current AS master, as the org.jboss.as:jboss-as-webservices-tests-integration would get the right version from the AS main pom.xml.
As a side note, this was the approach we've been using with AS 5/6 containers.
