This PR upgrades the tail sampling helm chart to use Grafana Alloy. This introduces breaking changes. See the README.md file.

In addition, it introduces a metricsGeneration.legacy configuration option set to true by default. In future releases, this will default to false. Using legacy metric names will align the spanmetrics generated by the otelcol.spanmetrics.connector component to match the metric names generated by the Tempo metrics generator. Setting metricsGeneration.legacy set to false will use the default metric names. See https://grafana.com/docs/agent/latest/flow/reference/components/otelcol.connector.spanmetrics/#otelcolconnectorspanmetrics for more info.

So It was only happening for a while. I suppose while the statefulset was warming up.
