Private extractors

In v1 extractors can send user ids to backend and only those users can use them. Can we do the same in v2?

• PyClowder recognizes environment variables EXTRACTOR_KEY and CLOWDER_EMAIL. the unique_key is used in the name of the queue: self.rabbitmq_queue = "private.%s.%s" % (extractor_key, self.rabbitmq_queue). email is injected inot the heartbeat: 'owner': self.clowder_email,
• The owner and unique_key are included in the extractor registration info in Clowder.
• Any API requests involving extractors honor these. If you submit file 123 to extractor wordcount...
  • If you include a unique_key and it matches a private one assigned to you, submit to that one.
  • If no key, it will route to a normal (public) wordcount if available.
