[docs request] how to create custom providers

[leobenzol]

Hey, I'm building a plugin to manage notifications from the dashboard as much as possible. To make it usable with most notification providers, I'd like to define my own "template provider" in my template module.
I got it working but it was quite a bit of boilerplate, which took sometime to find in the medusa repo and to figure out if I needed to store the providers in db, if i needed a default, how should i limit it to one provider per channel, how to properly define foreign keys to models supplied by providers etc...

I'd be nice to have a docs page with all the provider boilerplate in one place, an example of how to use them and an overview of possible modifications

Thanks for submitting this request! To clarify, you want to learn how to create a module that accepts providers, right?

Yes indeed
