Add RBAC policies for NetworkPolicy
**What this PR does / why we need it**:
When using RBAC, none of the namespace-level roles currently have permission to do anything with NetworkPolicy. (Only cluster-admin does, by virtue of having permission on "*".) This fixes it so "admin" and "edit" have read/write permission, and "view" has read-only permission.
I added permission for both the extensions and networking objects, which I believe is correct as long as both of them exist?
(This would be nice to fix in 1.9, although it's not a regression. It's always been broken.)
**Release note**:
```release-note
When using Role-Based Access Control, the "admin", "edit", and "view" roles now have the expected permissions on NetworkPolicy resources.

Fix a comment in hack/lib/version.sh about which tags are used to get the version

Alternatively, that flag could be removed from the command, but I think that requires more detailed thinking.

Ensure PVL controller is next pending initializer before labeling the PV
**What this PR does / why we need it**:
According the [documentation](https://kubernetes.io/docs/admin/extensible-admission-controllers/#how-are-initializers-triggered), initializer controllers should only initialize the object once its name is at `metadata.initializers.pending[0]`.[Currently](https://github.com/kubernetes/kubernetes/blob/master/pkg/controller/cloud/pvlcontroller.go#L268), the PVL controller just checks if its name is in the list at all and ignores ordering.

Hit ILB endpoint in e2e test
**What this PR does / why we need it**:
During the ILB e2e networking test, a pod is created and curls the ILB's IP address, validating that the load balancer correctly routes traffic to the K8s service. Test will also hit the external LB endpoint after switching from ILB->ELB, validating no GCE conversion issues going from ILB to ELB.
This does not validate that the load balancer is accessible externally to the cluster (but on the same network).

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 )

kubelet: include runtime error in event on CreatePodSandbox failure
