Replaces the instance label on prometheus metrics with the inventory hostname as opposed to the ip address. The ip address is still used as the target address which means that there is no issue of the hostname being unresolvable. Can be optionally enabled or set to FQDNs by changing the prometheus_instance_label variable as mentioned in the release notes.
