The validation webhook's health file updates and configuration reconciliation were invoked from the same goroutine. Delays in checking and updating the k8s configuration could result in the health file not being updated in time to pass the health checks. Use istio.io/istio/pkg/probe to decouple the two code paths.

* Improve config validation health checks (#7605) Readiness and liveliness probes were failing on some providers because GET requests were blocking for multiple seconds. Mitigate the issue by decreasing the frequency of GET (to avoid possible throttling) and increase the acceptable health check interval from 4s to 10s. Shorm term fix for #7586. Longer term fix requires switching to proper controller-style reconciliation. That work should be aligned with the sidecar injector. * decouple validation webhook's health checking and reconciliation loop (#7986) The validation webhook's health file updates and configuration reconciliation were invoked from the same goroutine. Delays in checking and updating the k8s configuration could result in the health file not being updated in time to pass the health checks. Use istio.io/istio/pkg/probe to decouple the two code paths.
