Save cognito_id_token in cookie

[Ulthran]

Not sure if these changes are within the scope of the package as you see it, but I had to spend a while learning about Cognito and the many ways of authenticating to AWS services so figured I'd include this to make it easier on the next.

FYI, my use case is an AWS Amplify app that I then want to have a separate flask site with access to all the components. Not sure if that should be mentioned in the docs or not.

Hey apologies for the delay in getting round to this - are you able to separate out the functional changes from documentation into separate PRs please?

Hi, is there any progress on this PR as it would be very beneficial and appears similar to that which was reported in issue #37? If I'd be willing to submit the PRs but would you be able to clarify the request

separate out the functional changes from documentation into separate PRs please?

Are you requesting the a PR for the changes to config.py and decorators.py in one PR and then the docs/accessing-aws-resources.md in a separate PR?

Done with #50!
