Adding request to user method

[JoeButler99]

Hi everyone, - I needed a method to add the request object to the call to get_or_create_for_cognito. I saw in one of the other pull requests this was also added.

I've created a crude system to do this, now I can receive from this library with
def get_or_create_for_cognito(self, jwt_payload, request):
in my manager model.

I am open to helping any suggestions to doing this in a better/cleaner way. (I'm also quite new to python packaging and its tooling..)
