Why does the integration belong in Magnum though? To me it belongs in the COEs themselves (e.g. their in-tree network/storage plugins) such that someone can leverage them regardless of their choices regarding COE deployment tooling (and yes that means Magnum should be able to leverage them too)? I guess the issue is that in the above conversation we are overloading the term "integration" which can be taken to mean different things...
