The `scrape-collectd` ConfigMap in the `default` namespace is used by
Victoria Metrics to identif the hosts from which it should scrape
collectd metrics. When deploying new machines that are _not_ part of
the Kubernetes cluster, we need to explicitly add them to this list.
The _host-provisioner_ can do this with an Ansible task, but it needs
the appropriate permissions to do so.
