Support running StatefulSetBasic e2e tests with local-up-cluster

Currently StatefulSet(s) fail when you use local-up-cluster without
setting a cloud provider. In this PR, we use set the
kubernetes.io/host-path provisioner as the default provisioner when
there CLOUD_PROVIDER is not specified. This enables e2e test(s)
(specifically StatefulSetBasic) to work.
