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, ...).

**Release note**:

ConfigMap objects now support binary data via a new `binaryData` field. When using `kubectl create configmap --from-file`, files containing non-UTF8 data will be placed in this new field in order to preserve the non-UTF8 data. Use of this feature requires 1.10+ apiserver and kubelets.

Fix autoscaling API documentation
**What this PR does / why we need it**:
This PR fixes the API documentation generated for HorizontalPodAutoscaler resource.
**Which issue(s) this PR fixes**:
The current API doc for `MetricSpec` and `MetricStatus` is confusing. Users get no idea what can be used as the value for the `type` field, because the doc says this:
```
type is the type of metric source. It should match one of the fields below.
```
While acceptable in the source code, it makes no senses when reading the API doc, especially when the "`type`" field is listed as the last row in a table (see: https://kubernetes.io/docs/api-reference/v1.8/#metricspec-v2beta1-autoscaling )
**Special notes for your reviewer**:
This PR makes no changes to the code behavior.
**Release note**:
```release-note
NONE
