StorageUploadTask implements resumable uploads to a file in Firebase Storage.
Uploads can be returned on completion with a completion callback, and can be monitored
by attaching observers, or controlled by calling pause(), resume(),
or cancel().
Uploads can be initialized from Data in memory, or a URL to a file on disk.
Uploads are performed on a background queue, and callbacks are raised on the developer
specified callbackQueue in Storage, or the main queue if unspecified.
