Extending the NiFi API

[DAVID SMITH]

Hi
At work we run many instances of NiFi and other associated data applications, 
with more instances of NiFi being planned it is becoming impracticable to use 
the UI's to add, delete users or amend their roles. We have developed an in 
house tool which controls these associated applications via their  API's .Could 
the NiFi API be extended to allow users to be added/removed or allow their 
roles to be updated. Thereby allowing us centrally manage many instances at 
once.
