What this PR does / why we need it:
The
detected_fieldsAPI accepts a full "logQL" query to be passed. This includes parsers. If parsers were passed, theSelectLogsstatement would parse labels into thestreamLabelsproperty. That would then cause thedetected_fieldslogic to run the "detection" logic again and append_extractedto all parsed labels.This PR changes the behavior: if parsed labels are returned by
SelectLogs, the API does not try to be smart and to parse again, but just return structuredmetadata and parsed labels. Theparsersreturned in that case will be the parsers used in the query.
