Configure cluster for e2e tests.

When KUBE_E2E_STORAGE_TEST_ENVIRONMENT is set to 'true', kube-up.sh script will: - Install the right packages for all storage volumes. - Use devicemapper as docker storage backend. 'aufs', the default one on Debian, does not support extended attibutes required by Ceph RBD and Gluster server containers. Tested on GCE and Vagrant, e2e tests for storage volumes passes without any additional configuration.

Configure cluster for e2e tests.
