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.

The rest of tests expect that the de-duplication is disabled.

8ed0d5471a lib/storage: correctly handle -dedup.minScrapeInterval values smaller than 8ms 
Such small values may be used for removing samples with duplicate timestamps.
See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/409 for details.
