Add healthz API

[flyer103]

Is your enhancement proposal related to a problem? Please describe.

Abnormalities may occur during the operation of the service, which needs to be detected and handled. Consider adding a healthz API to the Zadig services to provide queries on the health status of the component.

Describe the solution you'd like

We can consider using https://github.com/kubernetes/apiserver/tree/master/pkg/server/healthz in K8s to implement the healthz API.

Describe alternatives you've considered

None.

Additional context

For K8s-based systems, using methods similar to K8s will reduce learning costs.

Hi, @tbbrave, currently only two services, user and policy, have added the healthz API, and other components have not been added. For the architecture diagram, see architecture . For other components, are you interested in adding the healthz API? :D
