lib/logstorage: follow-up for 94627113db
- Move uniqueFields from rows to blockStreamMerger struct.
  This allows localizing all the references to uniqueFields inside blockStreamMerger.mustWriteBlock(),
  which should improve readability and maintainability of the code.

- Remove logging of the event when blocks cannot be merged because they contain more than maxColumnsPerBlock,
  since the provided logging didn't provide the solution for the issue with too many columns.
  I couldn't figure out the proper solution, which could be helpful for end user,
  so decided to remove the logging until we find the solution.

This commit also contains the following additional changes:

- It truncates field names longer than 128 chars during logs ingestion.
  This should prevent from ingesting bogus field names.
  This also should prevent from too big columnsHeader blocks,
  which could negatively affect search query performance,
  since columnsHeader is read on every scan of the corresponding data block.

- It limits the maximum length of const column value to 256.
  Longer values are stored in an ordinary columns.
  This helps limiting the size of columnsHeader blocks
  and improving search query performance by avoiding
  reading too long const columns on every scan of the corresponding data block.

- It deduplicates columns with identical names during data ingestion
  and background merging. Previously it was possible to pass columns with duplicate names
  to block.mustInitFromRows(), and they were stored as is in the block.

app/vlinsert: follow-up for d570763c91
- Switch from summary to histogram for vl_http_request_duration_seconds metric.
  This allows calculating request duration quantiles across multiple hosts
  via histogram_quantile(0.99, sum(vl_http_request_duration_seconds_bucket) by (vmrange)).
- Take into account only successfully processed data ingestion requests
  when updating vl_http_request_duration_seconds histogram.
  Failed requests are ignored, since they may significantly skew measurements.
- Clarify the description of the change at docs/VictoriaLogs/CHANGELOG.md.

app/vlinsert: add flag to limit amount of fields per line (#4976)
Adding limit on ingestion allows to avoid issues like this one https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4762
Such issues are often caused by misconfigurtion on log persing/ingestion side and preventing such rows from being ingested allows to avoid performance implications created by storing such log rows.

app/vlinsert/loki: follow-up after 09df5b66fd
- Parse protobuf if Content-Type isn't set to `application/json` - this behavior is documented at https://grafana.com/docs/loki/latest/api/#push-log-entries-to-loki

- Properly handle gzip'ped JSON requests. The `gzip` header must be read from `Content-Encoding` instead of `Content-Type` header

- Properly flush all the parsed logs with the explicit call to vlstorage.MustAddRows() at the end of query handler

- Check JSON field types more strictly.

- Allow parsing Loki timestamp as floating-point number. Such a timestamp can be generated by some clients,
  which store timestamps in float64 instead of int64.

- Optimize parsing of Loki labels in Prometheus text exposition format.

- Simplify tests.

- Remove lib/slicesutil, since there are no more users for it.

- Update docs with missing info and fix various typos. For example, it should be enough to have `instance` and `job` labels
  as stream fields in most Loki setups.

- Allow empty of missing timestamps in the ingested logs.
  The current timestamp at VictoriaLogs side is then used for the ingested logs.
  This simplifies debugging and testing of the provided HTTP-based data ingestion APIs.

The remaining MAJOR issue, which needs to be addressed: victoria-logs binary size increased from 13MB to 22MB
after adding support for Loki data ingestion protocol at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4482 .
This is because of shitty protobuf dependencies. They must be replaced with another protobuf implementation
similar to the one used at lib/prompb or lib/prompbmarshal .
