[Misc] Reduce logging cardinality of OTLP logger output
Description
Makes the main message simply say OTLP [INFO,ERROR,WARNING,...]. These corresponding log level in CTA never goes above WARNING (as telemetry is not critical for running the service).
The actual message from the OTLP logger is put in otlpMessage.
Any further attributes are populated from the attributemap.
