mgr/smb: add new ResourceKey protocol class

Add a new protocol class that can be used to uniquely identify a resource
within a given store namespace. The idea is to use this key class where
a resource can be ID'd by either one metadata field or by two allowing
more common interfaces and fewer special code paths.
