autocloud is dying soon. So, we want to run the tests in openQA
instead. This adds a test module called 'autocloud' and a test
suite called 'cloud_autocloud' which basically replicate what
autocloud does (download a tarball full of tests and run each
one), and the necessary template bits to run it on Cloud_Base
qcow2 images.
