auth via Google, Facebook

[k-stasevich]

Hello, I use react-cognito to work with auth state, and it is very useful, easy to use. Excellent! But I didn't find anything about auth via google/facebook. Do you plan to implement it?

What can you suggest for now to work with this? I could implement it with javascript sdk, provided by aws cognito documentation, but it is complicated because I am already have cognito reducer from react-cognito lib, and creating new one for managing state of autho via google/facebook. I don't like such splitting :(
