This configures the proxy to listen with TLS, with mutual TLS between it and the client, and vice versa. * Provided certificates with the repo to make it easy to run and connect to the proxy. * Two user certificates provided, with two different groups, with tests confirming unauthorized clients have their connection closed. * Certificates are generated with SAN that supports `localhost` and `127.0.0.1` for the server name.
