Add progress tracking for app uploads

[navin772]

Implement upload progress tracking and display it in console.

We can have a new cap - showUploadProgress = true that will enable this in the existing method. The upload method can be overloaded to support upload tracking.

Use OkHttp's native Sink and BufferedSink APIs to track progress.
