This is a different take at #45.

Instead of installing just the runroot builder plugin explicitly, here we
separate the plugins out into hub and builder plugins explicitly and install
each type in turn.

I see why you kept FILES, CONFDIR, and CONFFILES (minimizing the diff), but I think I'd rather be explicit, and change those to HUBFILES, HUBCONFDIR, and HUBCONFFILES.

Also, can we change BUILDERCONFDIR to /etc/kojid/plugins?

Done.

@ausil will need to be aware that the expected file location changed for the runroot.py plugin though, so we can adjust our Fedora-specific config in ansible.

+1

@mikeb, I don't have rights to merge this.

Can you do it and close #45 as well? It would be great to start cleaning out the PR queue here.

Changes like this need to be reflected in the spec file
