[PATCH] De-hardcode 'origin' as the remote name

[Mathieu Bridon]

By default, Git remotes are named 'origin', but some pyrpkg-based tools
might be used to interact with several remotes for the same package
module.

This change allows sites to define how remotes should be called by
simply overriding the Commands.remote attribute.

That attribute is set to "origin" though, to not break existing clones.

The rpkg bash completion resource had to be modified accordingly. Since
the fedpkg one already handles this properly, a simple copy-paste of
that specific line was enough.

This is important for us at $dayjob.

We have this rpkg-based tool called nbpkg, which we use to interact with
our packaging infrastructure, similar to fedpkg:

    https://github.com/network-box/nbpkg

But as I'm also a Fedora packager, I like to be able to interact with
both our internal infrastructure, and the Fedora one, in the same Git
clone, as it allows me to easily flow changes in both directions.

This workflow requires having different names for each remote though,
they can't just be all called 'origin'. This patch makes this possible.

I can imagine a similar use case for RHEL packagers, which could
probably want to interact with both the Fedora and RHEL packaging
infrastructures in the same Git clone, flowing changes both ways.

I know RPMFusion would be interested as well (I added Nicolas as CC).
