Add NominatedNodeName field to PodStatus
**What this PR does / why we need it**:
Today, Scheduler uses an annotation called "nominated-node-name" to mark a preemptor Pod. This annotation helps scheduler know about the Pods that are destined to run on the nodes so that the resources made available by preemption is not allocated to a different Pod. In a recent discussion with @bgrant0607, we learned that we should change the annotation to a field as this field can be used by multiple schedulers and other components that may make scheduling-related decisions (descheduler, auto-scaler, kube-arbitrator, ...).

api: validate container phase transitions
https://github.com/kubernetes/kubernetes/issues/54499 exposed an issue where a container was transitioning from the terminal phases of `Succeeded` or `Failed` to `Pending`. It is due to a bug in the kubelet, but additional validation in the API server can prevent this invalid phase transition from being accepted.
@smarterclayton @derekwaynecarr @dashpole @joelsmith @frobware
I confirmed that the reproducer in https://github.com/kubernetes/kubernetes/issues/54499 does not work with this validation in place. The erroneous kubelet status update is rejected:
```
status_manager.go:437] Failed to update status for pod "test_default(2f02ecdf-b92a-11e7-a2d0-1c1b0deeddfa)": Pod "test" is invalid: status.containerStatuses[0].state: Forbidden: may not be transitioned to non-terminated state
```
However, it only works to a point with this particular issue. The termination hangs and eventually the resource is removed from etcd and the status update goes through because there is no old statuses to compare. Not exactly sure how this happens since there is no pod in etcd anymore ¯\\_(ツ)_/¯
