If monitoring is enabled (via the *prometheus* plugin) then the following metric is exported:
* `coredns_reload_failed_count_total{}` - counts the number of failed reload attempts.
* `coredns_reload_version_info{hash, value}` - record the hash value during reload.
Currently the type of `hash` is "md5", the `value` is the returned hash value.
