Hi

I am proposing this new query API[1] for 7.0.0. Once it gets merged, the
following changes will remove the old p50-p99 metrics, like this

service_p99 = from(Service.latency).p99(10);
service_p95 = from(Service.latency).p95(10);
service_p90 = from(Service.latency).p90(10);
service_p75 = from(Service.latency).p75(10);
service_p50 = from(Service.latency).p50(10);

And relaced by
> service_pertentile = from(Service.latency).percentile(50,75,90,95,99)

Query side will use `service_pertentile` as metrics with the new API to get
full values.

Could you submit an issue of CLI to track this? Because p50 will not be
queryable from the old API anymore.
