Remove the noop deploystep for upgrade converge step

The noop deploystep is set during the prepare step for
upgrade. It put in the plan_env directly, so since we are
keeping the user-env / plan-env for upgrade the noop
steps are never removed.
This patch aim to trigger a mistral action to remove all
the OS::Heat::None for the deploystep/pre/post
