Cloud Base validation tests missing for Fedora 28 Beta

[Adam Williamson]

Hi folks! I noticed that none of the Base validation tests for Cloud
have been run for F28 Beta:

https://fedoraproject.org/wiki/Test_Results:Current_Base_Test

It'd be great if we could get those filled out. We are also missing the
Cloud validation tests for actual cloud environments (EC2 and
Openstack):

Note some Cloud images are still considered release blocking at
present:

so we do need these tests. Thanks!
