Summary:
We are updating our vizier phases to better match the lifecyle of our vizier.
also added a "reason" field, to match k8s' reasons, which the operator will use to track finer-grained states.

the next change will add healthcheck logic to the operator so that the operator's states will better match cloudconn's states.
