docIntel tasks failed for track/atg instance

On washington instances task processing fails with error NSE0014:Failed to initialize pipeline : No columns to parse from file (screenshot)

This is because, as part of security patch fix new roles are required to access docintel tables. 

1. Take Washington instance with version: Patch 4 or below.
2. install platform Document Intelligence plugin
3.install 3.0 docintel and 2.0 docintel admin App
4. go to the Use case and create a new use case under the Document extraction 
5.create a task and process it 

Issue : the Task is not getting processed. It failed with error
NSE0014:Failed to initialize pipeline : No columns to parse from fil

Add platform_ml_create role for sys_di_key_hint, sys_di_prediction_input, sys_di_ocr_input, sys_di_pdf_input, sys_di_training_input, sys_di_key, sys_di_key_group tables read acl's. 

This fix has been pushed to Washington patch 5.
