Feature Request: Forward auth requests from ALB to VR

[dankelly17]

We currently have an AWS ALB sitting in front of our Velociraptor server. The authentication also occurs at the ALB layer. Velociraptor currently does not contain a feature to either not have authentication, or forward the authentication from the ALB to the VR server.

The request is to add the capability to forward auth requests from the ALB to the VR gui so a user does not need to login two times.
