[keycloak-dev] Authentication with Google Identity Tokens aka Better Android support

TL;DR; How do I shove this : https://developers.google.com/identity/sign-in/web/backend-auth into KeyCloak. I've been reading up on how to extend the KeyCloak service and I want to write a (SPI? module? extension?) that let's me sign into my server services using a Google ID Token. This will let me use the Google account on my Android phone without ever having to open a web page. In fact if I only have one Google account on my phone I can automatically log my user into my app without ever having to prompt them. However, I'm not really sure where to start. I've cloned the keycloak repository and have been reviewing the code there and cross referencing with the docs, but I think I need a little more "push" in the right direction. For reference, I've implemented this flow in both Node.js and Java before without much trouble so I should be able to get a PoC up in an afternoon or two once I know where to put the code.
