Support to query QueryRange non-delta profiles buckets from FrostDB

[metalmatze]

Most of the work needs to be done in FrostDB: polarsignals/frostdb#347

parca/pkg/parcacol/querier.go

Lines 571 to 579 in ed90dbe

	// TODO: This still queries way too much data from the underlying database.
	// This needs to be moved to FrostDB to not even query all of this data in the first place.
	// With a scrape interval of 10s and a query range of 1d we'd query 8640 samples and at most return 960.
	// Even worse for a week, we'd query 60480 samples and only return 1000.
	tsBucket := ts / 1000 / int64(step.Seconds())
	if _, found := resSeriesBuckets[index][tsBucket]; found {
	// We already have a MetricsSample for this timestamp bucket, ignore it.
	continue
	}

This issue is mostly to keep track of updating Parca once the necessary parts have been implemented in FrostDB.
