Hosted domain Support

[marcelolebre]

I'm currently working on a project that requires google auth to be domain sensitive.

I decided to extend this implementation to support the hd param that allows this.

Hi there @marcelolebre,

Thank you for your interest in contributing to this library. After reviewing your pull request, it appears that the feature you are adding is not apart of the OAuth2 specification and does not pertain to all providers.

This library aims to only provide the building blocks for building OAuth2 clients. The strategies are defined as they are outlined in the OAuth2 spec and are meant to be built on top of.

What you seek can be achieved very easily with OAuth2.Client.put_param/3. Or by simply passing in the :hd option into your Google.authorize_url!(client, hd: "example.com") example.

hi @scrogson,

Thanks for the feedback. It felt weird to hardcode it as it's so widely used.

But I guess it makes sense to keep it true to the specs.
