45e770ed20 lib/cgroup: limit the maximum GOMAXPROCS value to the number of available CPU cores 
There is no sense in setting GOMAXPROCS to value higher than the number of available CPU cores.

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.

4b89da9463 lib/decimal: rename significant decimal digits to significant figures (#698) 
The previous notion was inconsistent with what `decimal.Round` does.
According to [wiki](https://en.wikipedia.org/wiki/Significant_figures) rounding
applied to all significant figures, not just decimal ones.
