Any plans for supporting appends to blobs? Our users are uploading files in pieces and right now we need to buffer it locally, and once the file is finished, upload into swift. we would like to upload into swift directly, bit by bit.

I know something like this is possible (uploading multiple blobs and having a manifest to combine hem all) but this assumes the multiple blobs are a certain, predetermined size. we want to append arbitrarily sized chunks.
