This change sets default = evaluation_interval similar to promtool
behavior.

(cherry picked from commit 683f8c2780)
In this case the _msg field is set to the value specified in the -defaultMsgValue command-line flag.
This should simplify first-time migration to VictoriaLogs from other systems.

(cherry picked from commit 96466562b6)
This msy be useful when ingesting logs from different sources, which store the log message in different fields.
For example, `_msg_field=message,event.data,some_field` will get log message from the first non-empty field:
`message`, `event.data` and `some_field`.
(cherry picked from commit ed73f8350b)
If the number of output (bloom, values) shards is zero, then this may lead to panic
as shown at https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7391 .
This panic may happen when parts with only constant fields with distinct values are merged into
output part with non-constant fields, which should be written to (bloom, values) shards.

"Single version" is unclear, since VM is also a single-executable. I
think "single-node" is clearer.

(cherry picked from commit 8dc4e2b5a5)
This allows reducing the amounts of data, which must be read during queries over logs with big number of fields (aka "wide events").
This, in turn, improves query performance when the data, which needs to be scanned during the query, doesn't fit OS page cache.
(cherry picked from commit 7a62eefa34)
This improves performance of `field_values` pipe when it is applied to large number of data blocks.
This also improves performance of /select/logsql/field_values HTTP API.

(cherry picked from commit 5d73b8b866)
It is possible for in-memory part to be empty if ingested samples are
removed by retention filters. In this case, data will not be discarded
due to retention before creating in memory part. After in-memory parts
merge samples will be removed resulting in creating completely empty
part at destination.
This commit checks for resulting part and skips it, if it's empty.
