otel-collector: add logging exporter configuration for traces
Created by: bobheadxi
This is not the export of logs, but the export of traces as logs. This can be the default configuration as we move towards the Sourcegraph 4.0 collector-without-jaeger configuration.
Test plan
sg.config.overwrite.yaml:
commands:
otel-collector:
env:
CONFIGURATION_FILE: 'configs/logging.yaml'
