This was unexpected behaviour for most users.

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: store the full response in stream parsing mode in scrapeWork.lastScrape byte slice 
This allows sending staleness marks and properly calculate scrape_series_added metric in stream parsing mode
at the cost of the increased memory usage, since now the potentially big response is kept
in the lastScrape byte slice per each scrapeWork.

In practice the memory usage increase shouldn't be big, since the response size
is usually much smaller than the parsed metrics from this response after the relabeling,
which usually adds a big pile of target-specific labels per each metric.

a1b298a842 app/vminsert/netstorage: disable rerouting by default 
Production clusters work more stable with the disabled rerouting during rolling restarts and/or
during spikes in time series churn rate. So it would be better disabling the rerouting by default.

The re-routing can be enabled by passing `-disableRerouting=false` command-line flag to `vminsert` nodes.

09670479cd lib/promscrape: reduce CPU usage for common case when calculating scrape_series_added metric 
Also reduce CPU usage when applying `series_limit` to scrape targets with constant set of metrics.

The main idea is to perform the calculations on scrape_series_added and series_limit
only if the set of metrics exposed by the target has been changed.
Scrape targets rarely change the set of exposed metrics,
so this optimization should reduce CPU usage in general case.

75c3514c5c lib/promrelabel: add keep_metrics and drop_metrics actions to relabeling rules 
These actions simlify metrics filtering. For example,

- action: keep_metrics
  regex: 'foo|bar|baz'

would leave only metrics with `foo`, `bar` and `baz` names, while the rest of metrics will be deleted.

The commit also makes possible to split long regexps into multiple lines. For example, the following config is equivalent to the config above:

- action: keep_metrics
  regex:
  - foo
  - bar
  - baz
