Enable a configurable whitelist of namespaces for V22

Browse source 
If a namespace is present in the whitelist, all calls are sent to the OCI model instead of the Pre OCI model

Note that this does increase overhead for registry calls (since we need to lookup the namespace for every single call), but it should only be temporary until we've migrated all users over to the OCI data model
