Fix service-loadbalancer test failures
Fix service-loadbalancer test failures

The previous test case of http://www.k8s.io is now failing becuase it
redirects to https://www.k8s.io, but the certificate being served for
that site isn't valid for that hostname anymore.  This changes it to use
the main kubenetes page which fixes the test failures.
