Subject: Make rollout status check best-effort, add poll

We cannot rely on the `watch.Until` call in the `rollout status`
subcommand for the time being, so we need to ignore the result of this
call. This will make the rollout status check best-effort, so we need to
follow it with a poll for the actual status of the rollout, which we can
extract from the `openshift.io/deployment.phase` annotation on the
ReplicationControllers. This annotation can have only three values --
`Running`, `Complete` and `Failed`. If we poll on this attribute until
we stop seeing `Running`, we can then inspect the last result for
`Failed`; if it's present, we have failed the deployment.
