create-testnet-data: take optional node configuration file as input and check/add genesis hashes and paths

[smelc]

Changelog

- description: |
    `create-testnet-data` now takes a node configuration file as input. If a file is given, it is augmented with the hashes (and paths) of the genesis files, or if the hashes/paths are present; they are checked.

This functionality should exist as a separate command

[Jimbo4350]

What is the use case for having these overrides? We are bundling too many things into a single command. addOrCheckHash gives us a hint that this can and should exist as separate command to check the node configuration file is correct and simply leave create-testnet-data to be responsible for creating a node configuration file. Otherwise we have all this additional logic that makes things unnecessarily more complex. This grows with the more "overrides" we put into a command.
