e933cbac16 lib/storage: postpone reading data from blocks during search
This eliminates the need for storing block data into temporary files on a single-node VictoriaMetrics
during heavy queries, which touch big number of time series over long time ranges.

This improves single-node VM performance on heavy queries by up to 2x.

a0000c3a6e lib/storage: improve deduplication algorithm
Now it leaves only the first data point on each `-dedup.minScrapeInterval` interval.

Previously it may leave two data points on the interval. This could lead to unexpected results
for `histogram_quantile(phi, sum(rate(buckets)) by (le))` query.

13b4069c59 lib/storage: postpone label filters matching too many time series instead of giving up with error
This should reduce the frequency of the following errors:

    cannot find tag filter matching less than N time series; either increase -search.maxUniqueTimeseries or use more specific tag filters

    more than N time series found on the time range [...]; either increase -search.maxUniqueTimeseries or shrink the time range
