[wildfly-dev] Chained transformers and 7.1.x tests

I’ve got the chained transformers mostly working in its own tests, but have some issues to iron out when using them for real, which is not picked up by the tests I wrote. Currently I am trying to convert the jmx subsystem, and think I will also do the other ones in wildfly-core (remoting and logging). Since we have disabled transformer testing against WildFly 8, and AS 7.1.x, there isn’t actually much of a chain to test at the moment. To get better coverage of what I have done in real subsystem scenarios, I would like to temporarily reinstate the test controller for 7.1.x, and to use a system property to enable running of tests against 7.1.x and WildFly 8 unless someone has some strong objections. If people start converting to use chained transformers, since the 7.1.x tests already exist, I think this will be valuable validation of what they are doing.
