Context aware refactoring

[ccoVeille]

I'm well aware of how the context could/should be used in a well designed application, but properly implementing it into the current codebase would be close to a full rewrite 🙈
So I opted to not try and change everything at once, but instead focus on the bits I wanted to add and make small improvements in the surrounding parts to make that possible.
I actually started with a function that returns a context in main, more of less exactly how you are proposing 😉, but the current layout of the app is not realy designed to work that way as it uses lots of global variables to store types (like the main Application type) that are being called from locations all over the code.
Properly restructering that in a more idiomatic layout would be a reasonably big change that should be a PR on itself in my opinion (and should be endorced by @jorgerojas26 as the owner/maintainer of this code).
Edit: Not proposing such a rewrite by the way! I like the tool and love to fix bugs that bug me or contribute features I'm missing, but I do have a (quite) busy day job as well 😊

Maybe the discussions we had here, could be quoted in a dedicated issue about a possible refactoring that would make the app more idiomatic, especially the context.

The issue might be closed then,but at least there will be a track of the discussion in an issue

That is a really good idea. I sadly did not know about Context api when i started building lazysql (remember this is my first touch on Go). So, that refactor would be a good idea.
