Automate NIFI flow and start processor group automatically

[#1]

Hi  , 

I want to automate my NiFi flow deployment process.
Currently, I have a NiFi template generator that works with multiple XML and configuration files where I define properties like Kafka topic names, broker IPs, and other NiFi-related settings. Using this template generator, I parse an existing sample NiFi XML template and generate a new XML file with all the required properties populated.

Right now, I upload this generated XML file manually through the NiFi UI. After that, I manually create a new process group on the NiFi canvas, import the template into this group, and then start the processor group and all required controller services.

I want to automate this entire flow—right from generating the template and creating the process group, to uploading the template into NiFi and starting the processors and controller services—so that no manual steps are needed in the NiFi UI.
