During the cache storage refactoring, all of the cache metrics that were recorded via the backend.Reporter that wrapped the cache backend were lost. This attempts to restore the metrics as close to the original meaning as possible, though due to the changes some labels are different and batch metrics don't apply. The biggest change is in the top requests metrics which has historically been based on the backend.Key, but since that the cache no longer deals with backends, the metric is now labeled by the resource kind. All existing dashboards and tctl top should still work as expected.
