[MERGE] --no-backup option for bzr upgrade (#118653)

[Lukáš Lalinský]

Hi,

I was browsing bzr bugs in launchpad and was very happy to notice
https://bugs.launchpad.net/bzr/+bug/118653, which explains that the only
thing that is preventing branches hosted on LP from being upgraded is
the .bzr.backup directory. So I added --no-backup option to `bzr
upgrade` to upgrade my branches, but as I expect it might be useful to
other people as well, I'm sending the patch also here.
