[ChatQNA] Support UI Authentication and HTTPS traffic encryption

[lucasmelogithub]

I understand that these are early days in the OPEA effort.

With that said, any plans to allow the option of protecting the ChatQNA UI with Authentication and HTTPS? https://github.com/opea-project/GenAIExamples/blob/main/ChatQnA/docker/ui/react/nginx.conf

Examples: https://docs.nginx.com/nginx/admin-guide/security-controls/configuring-http-basic-authentication/ https://nginx.org/en/docs/http/configuring_https_servers.html

Even as examples, it's not ideal to deploy open services and without on-the-wire encryption.
