- 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.

app/vmselect/netstorage: follow-up after 173ccf4333
- Clarify docs about -replicationFactor command-line flag at vmselect
- Clarify description for -replicationFactor and -search.skipSlowReplicas command-line flags
- Fix the logic for returning responses if -search.skipSlowReplicas command-line flag
  is enabled. The logic was broken in the 173ccf4333,
  so it could return responses only if some of vmstorage nodes return error,
  while it should return when query results are successfully collected from more than
  (len(storageNodes) - replicationFactor) vmstorage nodes.

vmselect: introduce search.skipSlowReplicas cmd-line flag ()
* vmselect: introduce `search.skipSlowReplicas` cmd-line flag

vmselect has two logical conditions during request processing when
`-replicationFactor` cmd-line flag is set:
1. If at least `len(storageNodes) - replicationFactor` responded, it could skip
waiting for the rest of nodes to respond. This could lead to problems described
here https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1207.
2. Mark response as partial if less than `len(storageNodes) - replicationFactor` responded
without an error.

The P1 showed itself error-prone and became the main reason why
`-replicationFactor` wasn't recommended to use at vmselect level.
However, this optimization could be still very useful in situations
when there are slow and fast replicas in cluster.

But P2 remains viable and important conditionless.
Hiding P1 behind the feature-flag `search.skipSlowReplicas`
should make `-replicationFactor` flag usable again. And let users
choose whether they want P1 to be respected.

app/vmstorage: deprecate -bigMergeConcurrency command-line flag
Improperly configured -bigMergeConcurrency command-line flag usually leads to uncontrolled
growth of unmerged parts, which, in turn, increases CPU usage and query durations.

So it is better deprecating this flag. In rare cases -smallMergeConcurrency command-line flag
can be used instead for controlling the concurrency of background merges.

- Use flag.Duration instead of flagutil.Duration for -snapshotCreateTimeout,
  since the flagutil.Duration is intended mostly for big durations, e.g. days, months and years,
  while the -snapshotCreateTimeout is usually smaller than one hour.
- Add links to https://docs.victoriametrics.com/#how-to-work-with-snapshots in docs/CHANGELOG.md,
  so readers could easily find the corresponding docs when reading the changelog.
- Properly remove all the created directories on unsuccessful attempt to create
  snapshot in Storage.CreateSnapshot().

vmselect/promql: check for deadline in count_values fn ()
* vmselect/promql: check for deadline in `count_values` fn

`count_values` could be very slow during the data processing.
Checking for deadline between iterations supposed to reduce
probability of exceeding `search.maxQueryDuration`.

The change also adds a new trace record, which captures the time
spent in aggregation function. Before that, the trace for aggr funcs
could be confusing since it doesn't account for all the places where
time was spent.

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/storage: subsitute searchTSIDs functions with more lightweight searchMetricIDs function
The searchTSIDs function was searching for metricIDs matching the the given tag filters
and then was locating the corresponding TSID entries for the found metricIDs.

The TSID entries aren't needed when searching for time series names (aka MetricName),
so this commit removes the uneeded TSID search from the implementation of /api/v1/series API.
This improves perfromance of /api/v1/series calls.

This commit also improves performance a bit for /api/v1/query and /api/v1/query_range calls,
since now these calls cache small metricIDs instead of big TSID entries
in the indexdb/tagFilters cache (now this cache is named indexdb/tagFiltersToMetricIDs)
without the need to compress the saved entries in order to save cache space.

This commit also removes concurrency limiter during searching for matching time series,
which was introduced in 8f16388428, since the concurrency
for all the read queries is already limited with -search.maxConcurrentRequests command-line flag.

Update docs ()
* deployment/docker: pass `-buildvs=false` to `go build` for production builds

This should resolve the `error obtaining VCS status: exit status 128` error
when the environment contains incorrect version of git or has incorrect access rights
to the directory with VictoriaMetrics source code.

See the following links for additional info:
- https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2508#issuecomment-1117126702 ,
- https://github.com/google/ko/issues/672
- https://github.com/golang/go/issues/49004

* lib/netutil: limit the number of concurrently established connections when calling ConnPool.Get()

This should reduce potential spikes in the number of established connections in the following cases:
- when the connection establishing procedure becomes temporarily slow
- after a temporary spike in the rate of ConnPool.Get() calls

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/2552

* docs/CHANGELOG.md: document c8af625bcc

See https://github.com/VictoriaMetrics/VictoriaMetrics/issues/1322#issuecomment-1120276146
