vmalert: integrate with victorialogs (#7255)
address https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6706.
See
https://github.com/VictoriaMetrics/VictoriaMetrics/blob/vmalert-support-vlog-ds/docs/VictoriaLogs/vmalert.md.

Related fix
https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7254.

Note: in this pull request, vmalert doesn't support
[backfilling](https://github.com/VictoriaMetrics/VictoriaMetrics/blob/vmalert-support-vlog-ds/docs/VictoriaLogs/vmalert.md#rules-backfilling)
for rules with a customized time filter. It might be added in the
future, see [this
issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7289)
for details.

Feature can be tested with image
`victoriametrics/vmalert:heads-vmalert-support-vlog-ds-0-g420629c-scratch`.

lib/logstorage: follow-up for 72941eac36
- Allow dropping metrics if the query result contains at least a single metric.
- Allow copying by(...) fields.
- Disallow overriding by(...) fields via `math` pipe.
- Allow using `format` pipe in stats query. This is useful for constructing some labels from the existing by(...) fields.
- Add more tests.
- Remove the check for time range in the query filter according to https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7254/files#r1803405826

victorialogs: add more checks for stats query APIs (#7254)
1. Verify if field in [fields
pipe](https://docs.victoriametrics.com/victorialogs/logsql/#fields-pipe)
exists. If not, it generates a metric with illegal float value "" for
prometheus metrics protocol.
2. check if multiple time range filters produce conflicted query time
range, for instance:
```
query: _time: 5m | stats count(), 
start:2024-10-08T10:00:00.806Z, 
end: 2024-10-08T12:00:00.806Z, 
time: 2024-10-10T10:02:59.806Z
```
must give no result due to invalid final time range.

lib/logstorage: disallow using pipe names as the first unquoted words in filter pipe
Improperly written pipes could be silently parsed as filter pipe.
For example, the following query:

   * | by (x)

was silently parsed to:

   * | filter "by" x

It is better to return error, so the user could identify and fix invalid pipe
instead of silently executing invalid query with `filter` pipe.

lib/logstorage: allow special chars in unquoted _stream tag names and values
This simplifies writing _stream filters. For example,

{foo-bar=abc:de}

can be written instead of

{"foo-bar"="abc:de"}

lib/logstorage: allow using ! in unescaped phrase
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.

lib/logstorage: support skipping _stream: prefix for stream filters
'_stream:{...}' can be written as '{...}'

This simplifies writing queries with stream filters, and makes them more familier to Loki users.

app/vlselect/logsql: clone the query with the current timestamp when performing live tailing requests in the loop
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.

lib/logstorage: add blocks_count pipe
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

app/vlselect: consistently reuse the original query timestamp when executing /select/logsql/query with positive limit=N query arg
Previously the query could return incorrect results, since the query timestamp was updated with every Query.Clone() call
during iterative search for the time range with up to limit=N rows.

While at it, optimize queries, which find low number of matching logs, while spend a lot of CPU time for searching
across big number of logs. The optimization reduces the upper bound of the time range to search if the current time range
contains zero matching rows.
