[WFLY-3154] : Operation which require server reload should check if something was changed.
Adding tests and modifying ReloadRequiredWriteAttributeHandler.
In the implementation we are comparing currentValue which is not a resolved with resolvedValue, this is done on purpose.
As the context might have changed we can't resolve currentValue being sure that the resolved value is the effective value.
