Summary

NIFI-14134 - add support for JSON file upload to CLI pg-import

Currently, in the CLI,

./cli.sh nifi pg-import

only supports creating a process group based on references to a versioned flow through a Registry Client.

In, the UI, it is possible to drag and drop a process group onto the canvas and provide a JSON file definition to create a new process group based on the flow definition. This approach should also be supported by the CLI command pg-import.

With this change, it is now possible to execute a command like below:

$ ./bin/cli.sh nifi pg-import -i /my/flow.json -p nifi-cli.properties
42357e56-0194-1000-7b1f-ba830cac1de6

And it returns the UUID of the process group created with the uploaded JSON flow definition.
