Please add health-check api when use HTTP basic authentication

[YueChenXu-Kimi]

When using ingress in GCP, load balancing needs to detect the health of back-end services, and the health check component must receive a 200 status code. However, after the basic authentication is used, the health check receives a 401 status code.

It is expected that a api can be independent. Whether basic authentication is used or not, 200 status codes can be returned normally.

Thanks.
