95ce89e7d7 lib/promscrape: use the number of parsed rows as a basis for writeRequestCtxPool leveling 
The previous basis on `cap(sw.labels)` doesn't work anymore after 7785869ccc ,
because `sw.labels` may be reset multiple times when processing big number of rows.

432c0383db Single dashboards update (#736) 
* dashboard: rename var `datasource` to `ds` for consistency reason

Dasbhoards for cluster version or vmagent operate with datasource variable
named `ds`. For consistency sake we rename this variable in single node version
as well.

* dashboard: add instance variable picker

See dashboard reviews here https://grafana.com/grafana/dashboards/10229/reviews

* dashboard: limit number of buckets in histogram to 12 for vmagent dashboard

* dashboard: bump version requirement in description for single version

* dashboard: drop extra series override for single version

* dashboard: set Y-min to zero for most of panels in vmagent dashboard

08b76cb26f vmalert: update -rule flag description to enforce quotes using (#709) 
Description for `-rule` flag uses as example specific chars like asterisks
which could be interpreted wrong by different shells. To avoid this, description
now contains quoted flag values.

34ef10fbcc lib/flagutil: avoid int overflow for arch 386 (#710) 
Arch 386 is a 32-bit architecture and interprets int type for numbers as an explicit int32,
whereas on most modern CPUs int is implicitly an int64. This makes tests to fail with
`int overflow` error.

9a77ae9d1c lib/promscrape: reduce memory usage when scraping targets with big number of metrics alongside targets with small number of labels 
Previously targets with big number of metrics and/or labels could generated too big buffers,
which then could be re-used when scraping targets with small number of metrics.
This resulted in memory waste.

Now big buffers are used only for targets with big number of metrics / labels,
while small buffers are used for targets with small number of metrics / labels.

applied to all significant figures, not just decimal ones.
