17b87725ed lib/promscrape/discovery/kubernetes: reduce memory usage when Kubernetes service discovery is configured on a big number of scrape jobs
Previously vmagent was creating a separate Kubernetes object cache per each scrape job.
This could result in increased memory usage when monitoring a Kubernetes cluster with big number of objects (pods / nodes / services, etc.)
as seen at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1113

Now it uses a shared map of scrape objects across multiple scrape jobs.
