app/vmselect/netstorage: pre-allocate 4 block references per each time series during querying

Usually the number of blocks returned per each time series during queries is around 4.
So it is a good idea to pre-allocate 4 block references per time series
in order to reduce the number of memory allocations.

Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3333
This fix is based on https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3620 ,
but doesn't slow down the common case with merging replicated data blocks so significantly.

lib/writeconcurrencylimiter: improve the logic behind -maxConcurrentInserts limit
...
Previously the -maxConcurrentInserts was limiting the number of established client connections,
which write data to VictoriaMetrics. Some of these connections could be idle.
Such connections do not consume big amounts of CPU and RAM, so there is a little sense in limiting
the number of such connections. So now the -maxConcurrentInserts command-line option
limits the number of concurrently executed insert requests, not including idle connections.
It is recommended removing -maxConcurrentInserts command-line option, since the default value
for this option should work good for most cases.

app/vmui: small usability improvements
...
- Show in the line tooltip the number of the query which generates the given line.
This simplifies comparison of lines generated by multiple queries.
- Show metric name as __name__ label in the line tooltip in the same way as other labels are shown there.
This makes the label information in the tooltip more consistent.
- Properly quote label values with JSON.stringify(). This prevents from improper formatting
when label values contain doublequote chars.
- Remove double curly braces artifact at graph legend for lines without names and labels.
- Properly use modifier for regular expressions across the code.

- Improve queries, so they return lower number of lines and labels.
This should improve metrics' exploration.
- Properly encode label filters and query args before passing them to VictoriaMetrics.

app/vmselect/promql: do not extend too short lookbehind window for rate() function if it is set explicitly

Previously too short lookbehind window d for rate(m[d]) could be automatically extended
if it didn't cover at least two raw samples. This was needed in order to guarantee
non-empty results from rate(m[d]) on short time ranges.
Now the lookbehind window isn't extended if it is set explicitly,
since it is expected that the user knows what he is doing.
The lookbehind window continues to be extended when needed if it isn't set explicitly.
For example, in the case of rate(m).
