lib/protoparser/csvimport: properly parse the last empty column in CSV line
...
Do not ignore the last empty column in CSV line.
While at it, properly parse CSV columns in single quotes, e.g. `'foo,bar',baz` is parsed as two columns - `foo,bar` and `baz`

Revert "lib/protoparser: fix skip csv line when metric can be collect from the line ( #4298 )"
...
This reverts commit 410ae99c2e
.
Reason for revert: the commit masks the real issue instead of fixing it.
The real issue is that the scanner.NextColumn() skips the last column if it is empty.
The commit also introduces two bugs:
- a panic if all the metric values in CSV line are empty
- silent import of CSV lines with too small number of columns

lib/protoparser/prometheus: move streamparser
to subpackage ( #3814 )
...
`lib/protoparser/prometheus` is used by various applications,
such as `app/vmalert`. The recent change to the
`lib/protoparser/prometheus` package introduced a new dependency
of `lib/writeconcurrencylimiter` which exposes some metrics.
Because of the dependency, now all applications which have this
dependency also expose these metrics.
Creating a new `lib/protoparser/prometheus/stream` package helps
to remove these metrics from apps which use `lib/protoparser/prometheus`
as dependency.

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.

lib/bytesutil: split Resize() into ResizeNoCopy() and ResizeWithCopy() functions
...
Previously bytesutil.Resize() was copying the original byte slice contents to a newly allocated slice.
This wasted CPU cycles and memory bandwidth in some places, where the original slice contents wasn't needed
after slize resizing. Switch such places to bytesutil.ResizeNoCopy().
Rename the original bytesutil.Resize() function to bytesutil.ResizeWithCopy() for the sake of improved readability.
Additionally, allocate new slice with `make()` instead of `append()`. This guarantees that the capacity of the allocated slice
exactly matches the requested size. The `append()` could return a slice with bigger capacity as an optimization for further `append()` calls.
This could result in excess memory usage when the returned byte slice was cached (for instance, in lib/blockcache).

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.

lib/protoparser/prometheus: properly parse metrics with exemplars

Examplars have been introduced in OpenMetrics - see https://github.com/OpenObservability/OpenMetrics/blob/master/OpenMetrics.md#exemplars-1
Previously VictoriaMetrics couldn't parse the following metric
foo{bar="baz"} 123 # exemplar here
This commit fixes this. Note that VictoriaMetrics ignores the exemplar as for now.
