Description

In NiFi there is a controller service to request OAuth2 tokens but this controller service cannot be referenced in any processor at this time. We should improve the InvokeHTTP processor so that it can use this controller service.

The controller service would use the a predefined client id and client secret in the controller service to make a request to an OAuth access serer to retrieve a token. The token would then be used by InvokeHTTP to perform the subsequent requests.
