clear init container status annotations when cleared in status

[sjenning]

When I pod with an init container is terminated due to exceeding its active deadline, the pod status is phase Failed with reason DeadlineExceeded. All container statuses are cleared from the pod status.

With init containers, however, the status is being regenerated from the status annotations. This is causing kubectl to report the pod state as Init:0/1 instead of DeadlineExceeded because the kubectl printer observes a running init container, which in reality is not running.

This PR clears out the init container status annotations when they have been removed from the pod status so they are not regenerated on the apiserver.
