Overview
This PR adds support for some additional headers to be propagated into claims in the authproxy connector.
What this PR does / why we need it
I am using Dex with authproxy to turn an existing IdP, whose code is not under my control, into an OIDC provider. I want to be able to propagate the user ID and email address from the underlying IdP as OIDC claims alongside the username, which is not possible with the current headers and claims supported by the authproxy connector.
This PR adds support for two extra headers that can be used to propagate the user ID and email from the underlying IdP, and sets the claims. When these additional headers are not set, it reduces to the previous mode.
