Add guide for Testflight and Android internal, alpha, and beta testing

[coreyshuman]

Getting an app setup in Android or Apple for internal and external testing takes Herculean effort. We should document this process on each platform. Screenshots would definitely be a plus, given how difficult both developer consoles are to navigate. Finally, adding a place for gotchas would be great (such as subscriptions not being available in iOS for testing if the client hasn't signed their tax agreement yet).

@Basim-Elayan you have a lot of experience with this process if you wanna tackle this. Maybe team up with another dev who has also worked done internal, alpha, and beta testing.

@coreyshuman I'll work on this one.

Is there any updates on this one?

Do we happen to have any sample Android/Apple projects we can use here?

[Basim-Elayan]

We have this project https://github.com/Shift3/row-forge-ns/wiki but unfortunately it's not complete and doesn't have everything we need, I added this task to my to do list.
