Chunking: change the default chunk size to 10MB

As discussed with Klaas, this seems to be a better compromise.
10MB * 3 prarralel jobs = 30MB in memory, and to retry in case of
disconnection. Which is still reasonable.  And might make the upload
almost twice as fast on fast network where the amount of chunk is the
bottleneck (because of more server processing)

Relates to issue #4354
