The parent jobs of the basic tempest jobs defined here enabled horizon since the merge of tempest-horizon into tempest (see Id2ced856a41548a0b49e594ee5fed6ed28785f24). But horizon is not really needed here, as the default list of tests does not incldue any horizon test. Disabling it helps freeing up a bit of resources for the job and also helps the ongoing effort of testing FIPS, which would otherwise require a patched django at this point. A similar change was applied to devstack-plugin-ceph, see review ID I05ea7f675aafb85eb54427ca95167b4c8f0eabdf Change-Id: I6f074ea0096b26da9a87b6df366c11c6f30ee48f
