Comment 1 for bug 1388047

Once I had an idea of detecting if Neutron is available during heat-engine start and simply not to register Neutron resources then (so they do not even show up in heat resource-type-list), but it turns out some deployments like TripleO do start heat before Neutron...

Also, especially for Nova-network/Neutron case, we have some resources that are "transparent" and use several clients, so there is no single "resource client".
