We have the e2e test with --deploy-rook=true that makes all test
environment. It works fine, but It does not seem to be the role of
e2e test. In addition, when developing the code we need to run full
test scenario with deploying rook every time, or we need to build
rook environment by hand. Move rook-deploy code to minikube.sh.
When rook-ceph is upgraded and changed some feature, e2e can be
failed. Change rook-ceph default verion to 'v1.1.2' explicitly
which is working fine in current code.
