That might not be 100% true, I was doing some cleanup that removed lots deprecated api in wildfly-controller master

In case some legacy versions subsystems ware using that api in 8.x it could break.

AFAIK there are only handful of cases that we ware using deprecated api in subsystems in 8.x but there ware few.

We can go on and use current test controller and later add 8.x if needed.
