Autodetect logging level

[tropnikovvl]

I rely on Loki's experience in this matter.

I send the same test logs to Loki and VMLogs and see that Loki automatically determines the log level, which allows me to make various filters by this field (for example, if these are not json logs).

Hi @tropnikovvl ! This detection was implement on the db side please check this PR

I will create a separate issue in the victoriametrics repository for such improvement

FYI: Auto-detection is problematic for the Logs volume chart because it’s built via /select/logsql/hits. That endpoint only groups by fields explicitly passed via field=..., so without a known level key you only get total volume.
