* Plugins: Add client middlware that forwards the signed grafana id token if present
* DsProxy: Set grafana id header if id token exists
* Add util function to apply id token to header
* Only add id forwarding middleware if feature toggle is enabled
* Add feature toggles to ds proxy and check if id forwarding is enabled
* Clean up test setup
* Change to use backend.ForwardHTTPHeaders interface
* PluginProxy: Forward signed identity when feature toggle is enabled
* PluginProxy: forrward signed id header
* Handle the response with different field key order
* More unit tests to cover edge cases
* Cover more edge cases
* make it simpler
* Better test inputs
- 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.
