Victoriametrics code does not work for victoriametrics cluster #6

See the docs here

I think you could test if cluster by calling:
${url}:8481/admin/tenants

the flags url would be:
${url}:8481/flags

and query for ${tenant} (the default is 0) would be:
${url}:8481/select/${tenant}/prometheus/api/v1/query?query=example

My current workaround is to set:
prometheus_url: http://vmselect-k8s-victoria-metrics-k8s-stack.monitoring.svc.cluster.local:8481/select/0/prometheus
