Final changes for RC2 based on sig-net review feedback

There are three changes here: 1. The "Prefix" path match type has been renamed "PathPrefix" to leave room for a future "StringPrefix" match. 2. The "ClassName" field in PolicyTargetReference has been removed as it is not clearly necessary at this point. 3. A new optional "Name" field has been added to ReferencePolicyTo, enabling more fine grained control over which resource(s) may be referenced.
