   As I see this is not solving 2 major issues which belongs to this area:
   * DTs not re-obtained which makes workloads fail after 7 days, please see 
[this](https://github.com/apache/flink/blob/4d19a9f09e58ae5726901b1c6c473b655d908440/flink-runtime/src/main/java/org/apache/flink/runtime/security/modules/HadoopModule.java#L89-L104)
 (I don't thing renew worth the hassle, we've seen this in Spark already, 
re-obtain is enough with less code).
   * DTs are not propagated to workers in a flexible but secure way
   
   Adding features and not solving these problems is a way we should't proceed.
