Work to make alpha more accessible

[cgwalters]

The /continuous stream has a very small target audience - basically people who want to test git master. But /alpha has potentially a much larger one, and I think we should get to the point where we say "Yes, it's totally sane to mix some alpha machines into your staging/production".

Tasks for that are the same baseline things for all release streams:

• Mirroring
• Signing
• Security updates (we should have a process to auto-respin alphas when underlying CentOS changes)

Perhaps the simplest here is that Alpha goes into the same ostree repo as downstream, and we at least place the qcow2/vagrant boxes in the same directories?

That makes sense to me. Do we like the name alpha? I've started getting used to it, but is it too bleeding edge sounding, or perhaps the right amount of bleeding edge sounding?
