Here is an issue that we need to investigate #6403

[codeboten]

Here's the PR to enable normalization by default: open-telemetry/opentelemetry-collector-contrib#20519, moving this PR back into draft until some of the work listed in #7454 is addressed

Did we migrate all the metrics? AFAIR, there are some components that still don't expose OTel metrics like exporter queue

@dmitryax There was a decision made at some point to use prometheus as a bridge for opencensus metrics. Today, when useOtelForInternalMetrics is enabled, both otel and opencensus are reporting metrics.

This is somewhat confusing in the code at this point, but it was a decision that prevented us from having to move all metrics to otel.
