Here's a new star on the deduplicating backup software sky: borgbackup.

Since it already entered many other linux distributions, it's time to
have it in a proper place for openSUSE as well.

One downside, I would like to note: this package depends on python >= 3.4,
which will exclude some older distributions and might depend on a few
other python3 packages, that aren't available for others. I will take care
of that with follow up SRs.
