Disk cache metrics require cache.enableDiskStatMetrics
After setting up the metrics-reporter-prometheus, I have missed entries
for caches/disk_cached and caches/disk_hit_ratio. Turns out they are
disabled by default via cache.enableDiskStatMetrics.
The feature flag comes from I41ee2d9a368c312b7b2729d17d6c19bee0d90922
which has been backported to all stable branches.
Add to the metrics documentation a reference to enableDiskStatMetrics
setting.
