Subject: [PATCH] scrape-collectd-configmap: Add PB

I didn't realize this playbook wasn't even in the Git repository when I
added it to `site.yml`.

This playbook manages the `scrape-collectd` ConfigMap, which is used by
Victoria Metrics to identify the hosts it should scrape to retrieve
metrics from _collectd_.
