JMX management model facade work
As part of ^ I rewrote the management model<->open mbean type conversion, since what I had before was terrible :-)
Update the subsystem archetype + docs to use the 7.0.1 org.jboss.as:jboss-as-subsystem-test subystem testing harness which was inspired by the 7.0.0 version of the archetype.
Start testing the JMX management model facade in AS and resolve any issues
PTO starting Wednesday, back on Thursday 1st.
