Server Logs Always Include Reserved Query ID Space for Easier Parsing

Official CH changelog text
There is always space reserved for query_id in the server logs, even if the log line is not related to a query. This makes it easier to parse server text logs with third-party tools.
Reserved space for query_id is added in all server log lines, even those not related to queries.

Why it matters

This feature ensures that every server log line consistently contains a query_id field. It simplifies parsing and analyzing server logs with third-party tools by providing a uniform log format.

How to use it

The feature is enabled by default in the server logging system, no additional configuration is required. Users will see a query_id field in every log line.
