lib/protoparser/opentelemetry: add metric to track skipped rows without resource (#5459)
Currently, it is impossible to understand why metrics are not ingested when resource is not set by OTEL exporter. Adding metric should simplify debugging and make it improve debuggability.

lib/protoparser/promremotewrite: fall back to zstd decoding if Snappy-decoding fails (#5344)
This case is possible after the following steps:
1. vmagent successfully performed handshake with the -remoteWrite.url and the remote storage supports zstd-compressed data.
2. remote storage became unavailable or slow to ingest data, vmagent compressed the collected data into blocks with zstd and puts these blocks to persistent queue on disk.
3. vmagent restarts and the remote storage is unavailable during the handshake, then vmagent falls back to Snappy compression.
4. vmagent starts sending zstd-compressed data from persistent queue to the remote storage, while falsely advertizing it sends Snappy-compressed data.
5. The remote storage receives zstd-compressed data and fails unpacking it with Snappy.

The solution is the same as 12cd32fd75, just fall back to zstd decompression if Snappy decompression fails.

lib/protoparser/promremotewrite: fall back to Snappy decoding if zstd decoding fails
This case is possible after the following steps:

1. vmagent tries to perform handshake with the -remoteWrite.url in order to determine whether
   the remote storage supports zstd-compressed data.
2. The remote storage is unavailable during the handshake. In this case vmagent falls back to Snappy compression
   for the data sent to the remote storage.
3. vmagent compresses the collected data into blocks with Snappy and puts these blocks to persistent queue on disk.
4. The remote storage becomes available.
5. vmagent restarts, performs the handshake with the remote storage and detects that it supports zstd-compressed data.
6. vmagent starts sending Snappy-compressed data from persistent queue to the remote storage,
   while falsely advertizing it sends zstd-compressed data.
7. The remote storage receives Snappy-compressed data and fails unpacking it with zstd.

The solution is to just fall back to Snappy decompression if zstd decompression fails.

lib/protoparser: handle unexpected EOF error when parsing lines in prometheus exposition format (#4851)

lib/protoparser/openetelemetry: fixes panic (#4821)
Opentelemetry format allows histograms with non-counter buckets. In this case it makes no sense to add buckets into database
and save only counter with _count suffix.
It could be used as gauge.

lib/protoparse/opentelemetry: reduce memory allocations

* wip

- Remove support for JSON parsing, since it is too fragile and is rarely used in practice.
  The most clients send OpenTelemetry metrics in protobuf.
  The JSON parser can be added in the future if needed.
- Remove unused code from lib/protoparser/opentelemetry/pb and lib/protoparser/opentelemetry/proto
- Do not re-use protobuf message between ParseStream() calls, since there is high chance
  of high fragmentation of the re-used message because of too complex nested structure of the message.

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.

csvimport: support empty values (#3565)
Before, if the imported line contained multiple metrics and one

Now, only metrics with empty values are ignored, and the rest
of the metrics are accepted successfully.

protoparser/opentsdb: allow lines without tags (#3303)
According to http://opentsdb.net/docs/build/html/api_telnet/put.html
"At least one tag pair must be present".
However, in VictoriaMetrics datamodel tags aren't required.
This could be confusing for users. Allowing accept lines without
tags seems to do no harm.
