Adjust concurrency logic and metrics in the concurrency package

[ShocOne]

Change

Reviewed and Adjusted Metric Calculations: Ensured that the error rate calculation is accurate and represents a meaningful metric for scaling decisions. This might include:
Averaging error rates over a rolling window of requests rather than accumulating persistently.
Resetting the error count on successful requests or adjusting how much weight is given to older errors.
Improve Logging: Enhance logging to provide more transparency about why decisions are made, especially around scaling. Log entries should reflect the success of ongoing operations and not just the status of previous errors unless those are directly relevant.
