 * BUGFIX: [Single-node VictoriaMetrics](https://docs.victoriametrics.com/) and `vminsert` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/cluster-victoriametrics/): reduce the default value for `-maxLabelValueLen` command-line flag from `16KiB` to `1KiB`. This should prevent from issues like [this one](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6176) when time series with too long labels are ingested into VictoriaMetrics.
