Schedules a new transfer to upload data to Amazon S3. This method is non-blocking and returns immediately (i.e. before the upload has finished).
When uploading options from a stream, callers must supply the size of options in the stream through the content length field in the ObjectMetadata parameter. If no content length is specified for the input stream, then TransferManager will attempt to buffer all the stream contents in memory and upload the options as a traditional, single part upload. Because the entire stream contents must be buffered in memory, this can be very expensive, and should be avoided whenever possible.
Use the returned Upload object to query the progress of the transfer, add listeners for progress events, and wait for the upload to complete.
If resources are available, the upload will begin immediately. Otherwise, the upload is scheduled and started as soon as resources become available.
