app/vmselect: limit the number of parallel workers by 32 (#5195) 
* app/vmselect: limit the number of parallel workers by 32

The change should improve performance and memory usage during query processing
on machines with big number of CPU cores. The number of parallel workers for
query processing is controlled via `-search.maxWorkersPerQuery` command-line flag.
By default, the number of workers is limited by the number of available CPU cores,
but not more than 32. The limit can be increased via `-search.maxWorkersPerQuery`.

* wip

- The `-search.maxWorkersPerQuery` command-line flag doesn't limit resource usage,
  so move it from the `resource usage limits` to `troubleshooting` chapter at docs/Single-server-VictoriaMetrics.md

- Make more clear the description for the `-search.maxWorkersPerQuery` command-line flag

- Add the description of `-search.maxWorkersPerQuery` to docs/Cluster-VictoriaMetrics.md

- Limit the maximum value, which can be passed to `-search.maxWorkersPerQuery`, to GOMAXPROCS,
  because bigger values may worsen query performance and increase CPU usage

- Improve the the description of the change at docs/CHANGELOG.md. Mark it as FEATURE instead of BUGFIX,
  since it is closer to a feature than to a bugfix.
