DioFirebasePerformanceInterceptor class

Dio client interceptor that hooks into request/response process and calls Firebase Metric API in between. The request key is calculated based upon extra field hash code which appears to be the same across onRequest, onResponse and onError calls.

Additionally there is no good API of obtaining content length from interceptor API so we're "approximating" the byte length based on headers & request data. If you're not fine with this, you can provide your own implementation in the constructor

This interceptor might be counting parsing time into elapsed API call duration. I am not fully aware of Dio internal architecture.
