docs/Single-server-VictoriaMetrics.md: document that the deduplication is applied only when exporting data in JSON line format
...
The exported data isn't de-duplicated by default due to performance reasons.
It is expected that the de-duplication is applied during importing the exported data.
The deduplication is applied only when exporting data via /api/v1/export if `reduce_mem_usage=1` query arg isn't passed to the request.

lib/promscrape: reduce memory usage if -promscrape.noStaleMarkers command-line flag is passed
...
Do not store in memory the response from the last scrape per each target if -promscrape.noStaleMarkers option is enabled.
This should reduce memory usage when the scraped targets return large responses.
