A recent proposed test to tempest was making explicit calls to the nova 
extension discovery api rather than using test.requires_ext. The reason 
was because we configure tempest.conf in the gate as 'all' for 
extensions, and the test involved an extension that was new in Juno. So 
the icehouse run failed. Since the methodology of branchless tempest 
requires that new conf flags be added for new features, we should stop 
having devstack configure with 'all'. Does any one disagree with that, 
or have a better solution?
