File segmentation to address large file error

[mmikitka]

While attempting to upload a 55GB file to OLRC, I received a "413 (Request Entity Too Large)" response and the upload aborted.

To upload the file, I used the Swift client with a 1M segment size: swift upload -S 1000000 container file

Should swiftclient.service.SwiftService.upload be used instead of swiftclient.client.put_object (the former supports segment_size, whereas the latter does not)?
