Subject: [PATCH] obnamlib: sftp: Add prefetch size argument
Paramiko made this argument required in v1.16. Details at
https://github.com/paramiko/paramiko/commit/49072f3537a8981e9d448c22481a1d2b92c03643
Attempt to fetch the entire file. I'm unsure if this is the original
intent. If the entire file isn't to be fetched, then the prefetch() is
probably not needed.
