Add device flow authorization support

[sealbro]

Hi, guys!

What do you think about supporting device flow authorization?

Configuration .well-known/openid-configuration contains device_authorization_endpoint
like {{KEYCLOAK_URL}}/realms/{{KEYCLOAK_REALM}}/protocol/openid-connect/auth/device

I think adding URL into providerJSON/Provider and a method like here for waiting for token

Hey!

The spec you're referring to (https://www.rfc-editor.org/rfc/rfc8628.html) is an OAuth 2.0 specification. It's not related to OpenID Connect (https://openid.net/developers/specs/).

This issue is likely better for Go's oauth2 repo: https://github.com/golang/oauth2

Going to close out since go-oidc is focused on OpenID Connect, not OAuth 2.0. But please re-open if I've misunderstood.
