Centralize the creation of the dialer during startup.
Have the dialer then passed in to both APIServer and Aggregator.
Aggregator the sets the dialer on its Transport base.
This should allow the SSTunnel to be used but also allow the Aggregation
Auth to work with it.
Depending on Environment InsecureSkipTLSVerify *may* need to be set to
true.
Fixed as few tests to call CreateDialer as part of start-up.
As part of https://github.com/kubernetes/community/pull/132, thsi commit
adds a generic webhook admission controller. This plugin allows for a
completely declarative approach for filtering/matching admission requests
and for matching admission requests, calls out to an external webhook for
handling admission requests.

Local storage plugin
**What this PR does / why we need it**:
Volume plugin implementation for local persistent volumes. Scheduler predicate will direct already-bound PVCs to the node that the local PV is at. PVC binding still happens independently.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*:
Part of #43640
**Release note**:
```
Alpha feature: Local volume plugin allows local directories to be created and consumed as a Persistent Volume. These volumes have node affinity and pods will only be scheduled to the node that the volume is at.

Certificate rotation for kubelet server certs.
Replaces the current kubelet server side self signed certs with certs signed by
the Certificate Request Signing API on the API server. Also renews expiring
kubelet server certs as expiration approaches.
Two Points:
1. With `--feature-gates=RotateKubeletServerCertificate=true` set, the kubelet will
request a certificate during the boot cycle and pause waiting for the request to
be satisfied.
2. In order to have the kubelet's certificate signing request auto approved,
`--insecure-experimental-approve-all-kubelet-csrs-for-group=` must be set on
the cluster controller manager. There is an improved mechanism for auto
approval [proposed](https://github.com/kubernetes/kubernetes/issues/45030).
**Release note**:
```release-note
With `--feature-gates=RotateKubeletServerCertificate=true` set, the kubelet will
request a server certificate from the API server during the boot cycle and pause
waiting for the request to be satisfied. It will continually refresh the certificate as
the certificates expiration approaches.

Kubeadm - Make code OS-agnostic
**What this PR does / why we need it**:
Kubernetes just got Windows Containers alpha support, opening the opportunity for kubeadm to also be used to setup, at least, Windows Server 2016 or newer worker nodes. With that in mind, we should take the effort of writing OS-agnostic code whenever possible, e.g. when dealing with the filesystem.

Protobuf generation for k8s.io/metrics
This PR introduces protobuf generation for k8s.io/metrics. Doing so required:
- fixing a bug in `go-to-protobuf` causing the `cast{key,value,type}` values to not be quoted when coming from struct tags (and not auto-injection by `go-to-protobuf` itself).
- Making sure the proto IDL in k8s.io/client-go had a package name of `k8s.io.client_go.xyz` and not `k8s.io.kubernetes.xyz`.
Additionally, I updated `go-to-protobuf` to skip functions and non-public types when composing the import list, which cuts down on the more bizarre imports in the IDL (like importing the sample API package in every IDL file because it contained `addToScheme`, like every other API package).
We use `castvalue` to force gogo-proto to realize that it should consider the value of the map which underlies `ResourceList` when calculating which imports need to be named. Otherwise, it ignores the value's type, leading to compilation errors when it later can't find an import it assumed existed. We accidentally didn't hit this in `k8s.io/kubernetes/pkg/api/v1` since another field coincidentally happens to directly use `resource.Quantity` (the value type of `ResourceList`).

Change to aggregator so it calls a user apiservice via its pod IP.
proxy_handler now does a sideways call to lookup the pod IPs for aservice.
It will then pick a random pod IP to forward the use apiserver request to.
**What this PR does / why we need it**: It allows the aggregator to work without setting up the full network stack on the kube master (i.e. with kube-dns or kube-proxy)

Add /healthz back to kube-proxy metrics server
Fixes#46447.
/healthz is removed from kube-proxy metrics server by #44968 and that breaks our upgrade test, which run 1.6 tests on 1.7 cluster. It seems harmless to continue holding /healthz on metrics server as well, so that we won't break other potential users.

**Release note**:

When using a `cast{key,value,type}` that was injected via struct tag, we
need to make sure to quote the value when transfering it over to proto
tags. Otherwise, it'll come through as unquoted, resulting in invalid
proto.
This was previously not a problem, since all values of `castkey` and
`casttype` were actually coming from the auto-injecting code which deals
with maps and aliases, which does correctly quote values.
This commit adds the `k8s.io/metrics` APIs to the list of packages for
which to generate protobuf. Additionally, it adds
`k8s.io/client-go/pkg/apis/v1` as a non-generated (referenced) package.
Since go-to-protobuf doesn't care about functions or private types (only
public types), we can skip them. This helps to clean up the generated
IDL: previously, the IDL contained erroneous imports due to matching
functions and private types which were not actually converted to protobuf,
but which were the same as functions and private types in other packages.
proxy_handler now uses the endpoint router to map the cluster IP to
appropriate endpoint (Pod) IP for the given resource.
Added code to allow aggregator routing to be optional.
Updated bazel build.
Fixes to cover JLiggit comments.
Added util ResourceLocation method based on Listers.
Fixed issues from verification steps.
Updated to add an interface to obfuscate some of the routing logic.
Collapsed cluster IP resolution in to the aggregator routing
implementation.
