Introduce a new flag that can be used to expose each DHCP lease as a specific metric. Given the high cardinality of these metrics, exposition of lease information is disabled by default. This feature takes cues from node_exporter collectors which are disabled by default, like the `processes` or `systemd` collectors for instance. Typically, high-cardinality metrics are against prometheus best-practices but for smaller networks (like home networks) these features can be quite powerful.

dnsmasq_exporter is an exporter for Prometheus, allowing you to monitor/alert on the number of DHCP leases and various DNS statistics.
The minimum required version of dnsmasq is 2.69, which added support for querying the statistics via DNS.
See also the “cache statistics” section in https://manpages.debian.org/stretch/dnsmasq-base/dnsmasq.8.en.html#NOTES
