Abiquo 5.4 introduces some changs to scopes to simplify tenant hierarchies.
First, when you assign a default scope to an enterprise, Abiquo will automatically add this enterprise to the scope.
Note that if you change the default scope of an enteprise, Abiquo will not remove the enterprise from the previous scope.
Secondly, to define a tenant hierarchy, Abiquo will use the default scopes of the enterprises only.
