Feature request: Add support for upload / download progress reporting

[ChristopherManthei]

Please add support for upload / download progress reporting.
E.g. the function upload_from_stream_async has no method for progress reporting when uploading large files. The C# equivalent does though: UploadFromStreamAsync.

Ideally all language SDKs should have feature parity so that users are allowed to chose the language that best fits their needs without later realizing that certain features do not work.

This sdk has been deprecated in favor of our next generation of storage C++ SDK https://github.com/Azure/azure-sdk-for-cpp. Usually we will only fix severe issues like security or data integrity, we won't add any new features.

Thanks @Jinming-Hu , we will look into migrating to the newer SDK. I have visited the landing page a couple of times but never noticed the comment at the start. Could you make it a bit more noticeable?

Also, could you add a disclaimer to the docs page: https://azure.github.io/azure-storage-cpp/index.html ? There is no mention of deprecation nor of the new library to use instead.
