- Removed RoleBinding and Webhook specific code in the namespacetransformer. That code was attempting to perform the task of the namereference - Updated namereference transformer configuration to suppport the Webhooks. - Prevent the namereference from wiping out the namespace value if no referral candidate was selected - Added unit tests.
