- The util/converter Prometheus response json parse was not checking for errors while parsing. It now does. In particular, if `[dataproxy]/response_limit` is set in Grafana's config, it will now recognize the limit error.
- Fixes#73747
- Adds `jsonitere` package, which wraps json-iterator/go's Iterator's Methods with methods that return errors, so errcheck linting can be relied upon
- Impact:
- If something was sending malformed JSON to the prometheus or loki datasources, the previous code might have accepted that and partially processed the data
- Before there may have been partial data with no error, where as no there may be errors but they will have no partial results, just the error.
