Automated Ubiquity Testing

[Max Brustkern]

We've got the main issues with the ubiquity tests running on regular Ubuntu
fixed and running in CI. I've got some jobs in my local instance as of
today, and I'm hoping to have them publishing to the cloud instance later
in the week. I'll send out an update when I get further on that, and I can
work on adding additional jobs and tweaking the frequency once the initial
ones are in good shape.
