Propagate upload: Change the default chunk size to 5MiB and make chunk upload parallel

Browse source 
The server is slow to process each chunk. As a result the time between
the chunks is not neglectible. Therefore we gain a lot of time by
uploading the chunks in parallel. So the bandwitdh is used when the
server is waiting between chunks.
