The new rule `MetricNameStatsCacheUtilizationIsTooHigh` will signalize about overutilization of Metric names usage stats tracker. See https://docs.victoriametrics.com/victoriametrics/#track-ingested-metrics-usage This rule can fire for deployments with high churn rate of metric names. In cases like this, it is better to disable metric name tracking completely, as it brings no use. It might fire for deployments that were tracking metric names for very long periods and this alert might be a good sign to reset the cache. ### Describe Your Changes Please provide a brief description of the changes you made.
