Run flow commands from plugin

[PRGfx]

I was thinking about having an infrastructure for executing flow commands to provide an action via the actions menu or line markers (i.e. for .*CommandController->.*Command methods or up and down in node-migrations).
I'm not quite sure if it would be possible to leverage the run/debug configurations (i.e. require the user to set up a run-configuration fitting for the project and then select this configuration in the plugin settings) in a way that actions could add parameters.
The more simple setup would probably be setting a working directory (defaulting to the project directory) and the script name (which could either be something like flow/flow.bat or a custom command to interface maybe with docker, like ddev exec ./flow).

But maybe most people have different approaches already working well.
