Istio mtls support and samples for stateful headless kubernetes services

Hi All,

I would like to implement Istio mtls support for stateful headless services like

  1. Cassandra
  2. Kafka - Zookeeper
  3. Storm

Does Istio support the above mentioned scenarios without any hacks today? If it does not support, is there a future release for which these features are planned for?

Thanks,
Sreeni
