[WFLY-3375] Fix address-setting inheritance

* WildFly address-setting must *not* be created using default values for
its attributes as they will override the values that are inherited using
HornetQ hierarchical repository of address settings.

* add a :resolve-address-setting operation to the hornetq-server
  resource to retrieve the *resolved* settings (i.e. as resolved by
  HornetQ after it merged all the the address settings matching the
  address).
