all: consistently use %w instead of %s in when error is passed to fmt.Errorf()
This allows consistently using errors.Is() for verifying whether the given error wraps some other known error.

lib/logstorage: follow-up for 8a23d08c21
- Compare the actual free disk space to the value provided via -storage.minFreeDiskSpaceBytes
  directly inside the Storage.IsReadOnly(). This should work fast in most cases.
  This simplifies the logic at lib/storage.

- Do not take into account -storage.minFreeDiskSpaceBytes during background merges, since
  it results in uncontrolled growth of small parts when the free disk space approaches -storage.minFreeDiskSpaceBytes.
  The background merge logic uses another mechanism for determining whether there is enough
  disk space for the merge - it reserves the needed disk space before the merge
  and releases it after the merge. This prevents from out of disk space errors during background merge.

- Properly handle corner cases for flushing in-memory data to disk when the storage
  enters read-only mode. This is better than losing the in-memory data.

- Return back Storage.MustAddRows() instead of Storage.AddRows(),
  since the only case when AddRows() can return error is when the storage is in read-only mode.
  This case must be handled by the caller by calling Storage.IsReadOnly()
  before adding rows to the storage.
  This simplifies the code a bit, since the caller of Storage.MustAddRows() shouldn't handle
  errors returned by Storage.AddRows().

- Properly store parsed logs to Storage if parts of the request contain invalid log lines.
  Previously the parsed logs could be lost in this case.

lib/logstorage: switch to read-only mode when running out of disk space (#4945)
* lib/logstorage: switch to read-only mode when running out of disk space

Added support of `--storage.minFreeDiskSpaceBytes` command-line flag to allow graceful handling of running out of disk space at `--storageDataPath`.

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/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 .
