This is the fourth in a series of changes to move to using the new oslo_<library> namespace that is being used for oslo libraries. There is currently a shim in place that is allowing the old oslo.<library> imports to work, but we need to be prepared for when the shims go away. Thus, we need patches like this one to move to the new namespace. This patch also updates our hacking check to ensure that no instances of oslo.utils sneak back in.
