WaitForNamedCacheSync synchronizes the informer's cache and will log a warning every minute if the operation hasn't completed yet, until it reaches a timeout of 10 minutes. Under normal circumstances, the cache sync should be fast. If it takes more than 1 minute, it means that something is stuck and the message will indicate to the admin which informer is the culprit. See https://github.com/prometheus-operator/prometheus-operator/issues/3347.
