nova-cert is only needed for 1 API resource (os-certificates) and the ec2 api. We don't need to run it on all the other functional tests. Getting rid of a service start / stop on all of them shaves a little time off each test, and means noise in logs. Change-Id: I175b8913fe5d19c8b552c60c793565c042c6b874
