I've spent some free time working on a Riak impl of apiman's components, and it became clear that we have some policies which use the simple state context for simple local-only operations (e.g. CORS). This is an incredibly expensive/wasteful use of a distributed data store.

We should add a local-only (i.e. same-node only) map - essentially identical to the memory only impl but available as separate methods (getPropertyLocal, setPropertyLocal, clearPropertyLocal)
