Fix PodPidsLimit and ConfigTrialDuration on internal KubeletConfig type
They should both follow the convention of not being a pointer on the internal type.
This required adding a conversion function between `int64` and `*int64`. A side effect is this removes a warning in the generated code for the apps API group.

**Special notes for your reviewer**:
**Release note**:
```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.

Separate loop and plugin control

Adding an "--external-plugin" flag to specify a plugin to load when

that the cloud provider and external plugin flags would go away once
all cloud providers are on stage 2 cloud-controller-manager solutions.

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)_/¯

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.
