[exporter/loki] Do not promote log level to loki label

[mar4uk]

Component(s)

exporter/loki

Is your feature request related to a problem? Please describe.

Currently, if the log record has a severityNumber attribute, lokiexporter adds level label corresponding to the severityNumber: see the mapping here

For example, if the log record has the attribute severityNumber=plog.SeverityNumberDebug4 label level=DEBUG4 would be added in Loki

It is not a good practice to promote log level to the label in Loki.

Describe the solution you'd like

level shouldn't be promoted to loki label automatically

Describe alternatives you've considered

Removing needs triage as this was filed by a code owner and it makes sense from links provided.

Thanks for including relevant links, very clear and easy to understand!

I'm a little bit delaying on this one to make sure we aligned with native loki otlp enpoint

Since the loki exporter is going to be deprecated soon in favor of otlp exporter (Loki now supports otlp), I don't think we should make new changes to the loki exporter.

Will close this issue
