Support for mTLS Configuration in MCP Gateway

[CBechert]

Hi, I'm exploring mTLS support for the MCP Gateway.
The deployment guide mentions TLS termination at the ALB and using Caddy/Nginx in-container under "Security Tips." I'm interested in implementing mTLS for client authentication. Are there plans to support mTLS, and are there detailed instructions or example configurations (e.g., Caddyfile or Nginx) for setting it up in the container?

Thank you!
