## What changed? <!-- Describe what has changed in this PR --> - Add backward compatibility configs for tally to otel migration ## Why? <!-- Tell your future self why have you made these changes --> - There are some breaking changes when switching from tally to otel metric framework. 1. Unit name will be appended to the metric name 2. `_total` will be appended to counter metrics 3. Timer metric will be emitted as milliseconds instead of seconds This PR adds configs for controlling both behaviors when using otel framework so that the behavior will be the same as tally. ## How did you test it? <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> - Unit tests - Tested locally with various combination of configurations. ## Potential risks <!-- Assuming the worst case, what can be broken when deploying this change to production? --> - No risk by default. If new options are enabled, timer metric value may be wrong or not bucketed correctly. ## Documentation <!-- Have you made sure this change doesn't falsify anything currently stated in `docs/`? If significant new behavior is added, have you described that in `docs/`? --> ## Is hotfix candidate? <!-- Is this PR a hotfix candidate or does it require a notification to be sent to the broader community? (Yes/No) --> - No.
