Previously the phrase filter with `!` was treated unexpectedly.
For example, `foo!bar` filter was treated at `foo AND NOT bar`,
while most users expect that it matches "foo!bar" phrase.
This commit aligns with users' expectations.
encoding.GetUint64s() returns uninitialized slice, which may contain arbitrary values.
So values in this slice must be reset to zero before using it for counting hits in `uniq` and `top` pipes.
This simplifies pipeProcessor initialization logic a bit.
This also doesn't mangle the original maxStateSize value, which is used in error messages when the state size exceeds maxStateSize.

This allows executing queries with `stats` pipe, which calculate multiple results with the same functions,
but with different `if (...)` conditions. For example:
_time:5m | count(), count() if (error)
Previously such queries couldn't be executed becasue automatically generated name for the second result
didn't include `if (error)`, so names for both results were identical - `count(*)`.
Now the following queries are equivalents:
_time:5s | sort by (_time)
_time:5s | order by (_time)
This is needed for convenience, since `order by` is commonly used in other query languages such as SQL.

Before, single and cluster deployments were provisioned with both
Grafana datasources: single and cluster. But this resulted into a
problem: single DS didn't work for cluster and vice versa. See
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7113
This PR splits datasource file into 2 files: single and cluster. Now,
these files are separately provisioned to single and cluster deployments
correspondingly.

(cherry picked from commit c896bf340d)
Previously only logs inside the selected time range could be returned by stream_context pipe.
For example, the following query could return up to 10 surrounding logs only for the last 5 minutes,
while most users expect this query should return up to 10 surrounding logs without restrictions on the time range.
_time:5m panic | stream_context before 10
This enables the ability to implement stream context feature at VictoriaLogs web UI: https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7063 .
Reduce memory usage when returning stream context over big log streams with millions of entries.
The new logic scans over all the log messages for the selected log stream, while keeping in memory only
the given number of surrounding logs. Previously all the logs for the given log stream on the selected time range
were loaded in memory before selecting the needed surrounding logs.
This should help https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6730 .
Reduce the scan performance for big log streams by fetching only the requested fields. For example, the following
query should be executed much faster than before if logs contain many fields other than _stream, _msg and _time:
panic | stream_context after 30 | fields _stream, _msg, _time
Use local timezone of the host server in this case. The timezone can be overridden
with TZ environment variable if needed.
While at it, allow using whitespace instead of T as a delimiter between data and time
in the ingested _time field. For example, '2024-09-20 10:20:30' is now accepted
during data ingestion. This is valid ISO8601 format, which is used by some log shippers,
so it should be supported. This format is also known as SQL datetime format.
Also assume local time zone when time without timezone information is passed to querying APIs.
Previously such a time was parsed in UTC timezone. Add `Z` to the end of the time string
if the old behaviour is preferred.

### Describe Your Changes
VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785
This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.
New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.
Example log output:
```
2024-09-23T02:33:19.719Z warn app/vlinsert/insertutils/common_params.go:189 dropping log line without _msg field; [{@timestamp 2024-09-18T13:42:16.600000000Z} {Attributes.array.attribute ["many","values"]} {Attributes.boolean.attribute true} {Attributes.double.attribute 637.704} {Attributes.int.attribute 10} {Attributes.map.attribute.some.map.key some value} {Attributes.string.attribute some string} {Body Example ddddddddddlog record} {Resource.service.name my.service} {Scope.my.scope.attribute some scope attribute} {Scope.name my.library} {Scope.version 1.0.0} {SeverityNumber 10} {SeverityText Information} {SpanId eee19b7ec3c1b174} {TraceFlags 0} {TraceId 5b8efff798038103d269b633813fc60c}]

Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted
in stopped live tailing, since new logs have timestamps bigger than the original time range.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7028
This pipe is useful for debugging purposes when the number of processed blocks must be calculated for the given query:
<query> | blocks_count
This helps detecting the root cause of query performance slowdown in cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070
This improves performance for analytical queries, which do not need column headers metadata.
For example, the following query doesn't need column headers metadata, since _stream and min(_time)
are stored in block header, which is read separately from colum headers metadata:
_time:1w | stats by (_stream) min(_time) min_time
This commit significantly improves the performance for this query.
