[AZINTS-3895] Trigger LFO script from quickstart

[benjjs]

Summary

Add a step to the quickstart script to create or update the log forwarder. Since we already have a log_forwarders step to collect the existing log forwarders, I've named this one upsert_log_forwarder. We perform this step only if we get a non-empty log forwarding config as part of the user selections.

Since the LFO script wants scopes in terms of subscriptions only, we flatten management groups into subscriptions and dedup before passing them as part of the log forwarder config.

In order to invoke the script from this script, I've separated out the business logic from the command line arg parsing in the main function.

Testing

I made some temporary modifications for testing purposes:

• Pass only one LFO so that we are allowed to toggle log forwarding
• Don't actually invoke the script since it isn't quite ready for our use case
• Skip the steps to create an app registration
• Add some prints

Then connected the script and submitted with log forwarding enabled:

Note that the log forwarder settings came through and the loading text is correct.

Now try submitting with log forwarding disabled:

Note that we do not enter the step.

lgtm, left a few comments. One thing to keep in mind moving forward is that setup.py is getting big. Now that we have zipapp working, consider breaking up or adding new logic into new files.

Yeah once I'm done with the launch blockers that is definitely something I want to do.
