Azure cloud provider: expose services on non-default subnets
**What this PR does / why we need it**: The Azure cloud provider allows users to specify that a service should be exposed on an internal load balancer instead of the default external load balancer. However, in a VNet environment, such services are currently always exposed on the master subnet. Where there are multiple subnets in the VNet, it's desirable to be able to expose an internal service on any subnet. This PR allows this via a new annotation, `service.beta.kubernetes.io/azure-load-balancer-internal-subnet`.
**Which issue this PR fixes**: fixes https://github.com/Azure/acs-engine/issues/1296 (no corresponding issue has been raised in the k8s core repo)
**Special notes for your reviewer**: None
**Release note**:
```release-note
A new service annotation has been added for services of type LoadBalancer on Azure,
to specify the subnet on which the service's front end IP should be provisioned. The
annotation is service.beta.kubernetes.io/azure-load-balancer-internal-subnet and its
value is the subnet name (not the subnet ARM ID). If omitted, the default is the
master subnet. It is ignored if the service is not on Azure, if the type is not
LoadBalancer, or if the load balancer is not internal.

Fix AnnotationProvidedIPAddr annotation for externalCloudProvider
**What this PR does / why we need it**:
In #44258, it introduced `AnnotationProvidedIPAddr`. When kubelet has 'node-ip' parameter set, and cloud provider not set, this annotation would be populated, and then will be validated by cloud-controller-manager:
https://github.com/kubernetes/kubernetes/pull/44258/files#diff-6b0808bd1afb15f9f77986f4459601c2R465
Later with #47152, externalCloudProvider is checked and func returns before that annotation got set. In this case, that annotation will not get populated.
This fix is to bring that annotation assignment to a proper location.
Please correct me if I have any misunderstanding.

Adds a command-line argument to kube-apiserver called

reconciler uses the storageapi and a TTL to keep alive an endpoint within the
`kube-apiserver-endpoint` storage namespace. The 'none' reconciler is a noop
reconciler that does not do anything. This is useful for self-hosted
environments.

kubectl: Fix golint warnings for plugins/*
**What this PR does / why we need it**:
We currently have an entry in `hack/.golint_failures` for `pkg/kubectl/plugins`. If we lint the files in `plugins/` then we can safely remove this entry.
`golint` emits the following warnings (only one of each type shown)
```
exported method EnvList.Slice should have comment or be unexported
error var IncompletePluginError should have name of the form ErrFoo
func name will be used as plugins.PluginsEnvVarPluginLoader by other packages, and that stutters; consider calling this EnvVarPluginLoader
```
This PR clears all `golint` warnings from `kubectl/plugins/`.
1. Remove entry from `hack/.golint_failures`
2. Add missing documentation to exported types and functions.
3. Rename error variables to `ErrFoo`.
4. Rename `PluginsEnvVarPluginLoader` to `KubectlPluginsPathPluginLoader` (mirrors env var name).
5. Rename `XDGDataPluginLoader` to `XDGDataDirsPluginLoader` (to make uniform change above).
**Special notes for your reviewer**:
Felt a bit dirty doing this cleanup because the code in `plugins/` is particularly clean and well written already.

kubelet: fix inconsistent display of terminated pod IPs
PLEG and kubelet race when reading and sending pod status to the apiserver. PLEG
inserts status into a cache, and then signals kubelet. Kubelet then eventually
reads the status out of that cache, but in the mean time the status could have
been changed by PLEG.
When a pod exits, pod status will no longer include the pod's IP address because
the network plugin/runtime will report "" for terminated pod IPs. If this status
gets inserted into the PLEG cache before kubelet gets the status out of the cache,
kubelet will see a blank pod IP address. This happens in about 1/5 of cases when
pods are short-lived, and somewhat less frequently for longer running pods.
To ensure consistency for properties of dead pods, copy an old status update's
IP address over to the new status update if (a) the new status update's IP is
missing and (b) all sandboxes of the pod are dead/not-ready (eg, no possibility
for a valid IP from the sandbox).
