Bring back the possibility of exporting and importing menus directly using drush

I pushed the initial changes, drush updb needs to be run.
I'm setting the issue status to Needs work while I work on updating the README file and test on multiple versions.

Outstanding work! I tried it and it worked really well: I added the patch, ran drush updatedb, exported and imported a menu. Everything went smoothly, so as far as I can tell, it works perfectly.

There were a few details in the documentation, about using full commands vs. aliases. But that's a very minor issue. I added comments and suggestions, and if you agree with them, you should be able to simply commit my suggestions via the Gitlab GUI.

Thanks again, this is great!

Thank you for your feedback, I was expecting feedback especially in this direction, so that's perfectly fine.
I do prefer aliases due to faster typing, so I might just mention both to cover both. I'll be back.

@ressa thank you as always!
Marking as Fixed.

Thanks @bbu23, this is perfection!

Actually, I have been thinking more about this, and I think the GUI part should maybe be removed, for a more "pure" Drush integration ... I created a follow up issue.

Thanks @ressa. You know, I was a bit surprised that in your yesterday's feedback there was nothing about this. Because I had troubles naming it hahah

My dilema was that I didn't want to have something that says "this is the only Drush option". Because, as we both know, Drush is available in both scenarios. The only difference is that this "quick export" is offering codebase only Drush commands that can be used immediately with minimal configuration if the user wants to change it, whereas for more stable/regular imports/exports, the user would have to go through multiple steps to be able to use Drush if they want.

So, my question is: if we call it "Drush Export/Import", isn't it implying that this section is the only Drush section available? That's where I added "quick". Now, I was not necessarily pleased by the "Action" name, I added this because I was thinking that it reduces "Import/Export" into one word, but it is not ideal. Also, I was thinking of potentially creating a form of "quick action" (let's say) or two forms "quick import" and "quick export" to import/export on the fly menus using GUI and using the contents of the Configuration Entities for one time situations. Like maybe when I want to quickly download a menu from production, instead of creating a config entity before, to have this possibility. And that's how I arrived to that.

The --format option will be added to the new commands based on the discussion in the related ticket.

The eternal challenge of naming things is rearing its ugly head again!

I get your dilemma, since the other option of import/export also has Drush integration, in its own way ...

Thanks for elaborating with your thoughts behind the naming. After all is considered, maybe it should stay named as it is, but the description below could feature the word "Drush" prominently and explain how it is different? Maybe something along these lines?

Quick Action Settings
Drush-driven exports and imports, for a faster process.

I like it!

Yes, naming naming... :D

Perfect, in this case I'll use that description, it's perfect. And update the format. Thanks!

You're welcome, thanks!

The format option has been added and the menu description updated.
This should resolve the remaining feedback.
Thank you!

Actually, I forgot to update the README. Reopening.
