altsrc: Set flags without erroring out.

[HaoZeke]

Basically I was wondering if there is a method to set flags only if the .yml file exists.

Currently it errors out (naturally, as the call is in app.Before) if the file is missing.

Is there any other way other than creating a default .yml file before checking for it?

Hiya! There's a known issue with the current implementation of the CLI, where altsrc is generally clunky and poorly documented. My current idea is that I'm going to move all of the altsrc functionality into the main package in some way, and that's how all of the "altsrc is weird and different???" issues people are having will get resolved. I'm tracking that work here => #833

I don't know if it's a good idea to close a bunch of issues without discussing and implementing fixes. It's counter intuitive and goes against the whole point of opening and reporting issues in the first place.

[HaoZeke]

These should ideally be kept open until they are resolved. It streamlines the discussion. A meta issue like the one you opened is not a bad idea either but not at the cost of the focused discussions which might take place on the original issue.

I disagree, if there is a general theme in a lot of issues, they should follow a general issue.

[HaoZeke]

Well, altsrc being weird and needing to be fixed is far too general a theme in my opinion, but then I've not used cli in ages anyway.

It qualifies as a general theme in this particular case because I'm proposing we completely remove altsrc - which would make all the altsrc issues either disappear ✨ or become invalid since the code has changed so much 🌀
