Remove the deprecated --babysit-daemons kubelet flag
```release-note
Removes the deprecated kubelet flag --babysit-daemons
```
This flag has been deprecated for over a year (git blame says marked deprecated on March 1, 2016).
Relatively easy removal - nothing in the Kubelet relies on it anymore.
There was still some stuff in the provisioning scripts. It was easy to rip out, but in general we probably need to be more disciplined about updating the provisioning scripts at the same time that we initially mark things deprecated.

Disabling service-dns controller for federation kubectl tests
**What this PR does / why we need it**:
DNS was unnecessary to do kubectl tests against federation, but it was required earlier as service-controller would not start without initializing dns-provider. Now since we have the capability to disable service-dns controller, we no longer need to initialize federation-controller-manger with DNS specific stuff. So removing it.

Add an AEAD encrypting transformer for storing secrets encrypted at rest
Tweak the ValueTransformer interface slightly to support additional
context information (to allow authenticated data to be generated by the
store and passed to the transformer). Add a prefix transformer that
looks for known matching prefixes and uses them. Add an AES GCM
transformer that performs AEAD on the values coming in and out of the
store.
Implementation of https://docs.google.com/document/d/1lFhPLlvkCo3XFC2xFDPSn0jAGpqKcCCZaNsBAv8zFdE/edit# and https://github.com/kubernetes/kubernetes/issues/12742

Apiregistration v1alpha1→v1beta1
Promoting apiregistration api from v1alpha1 to v1beta1.
API Registration is responsible for registering an API `Group`/`Version` with
another kubernetes like API server. The `APIService` holds information
about the other API server in `APIServiceSpec` type as well as general
`TypeMeta` and `ObjectMeta`. The `APIServiceSpec` type have the main
configuration needed to do the aggregation. Any request coming for
specified `Group`/`Version` will be directed to the service defined by
`ServiceReference` (on port 443) after validating the target using provided
`CABundle` or skipping validation if development flag `InsecureSkipTLSVerify`
is set. `Priority` is controlling the order of this API group in the overall
discovery document.
The return status is a set of conditions for this aggregation. Currently
there is only one condition named "Available", if true, it means the
api/server requests will be redirected to specified API server.
```release-note
API Registration is now in beta.

Support running StatefulSetBasic e2e tests with local-up-cluster
**What this PR does / why we need it**:
Currently StatefulSet(s) fail when you use local-up-cluster without
setting a cloud provider. In this PR, we use set the
kubernetes.io/host-path provisioner as the default provisioner when
there CLOUD_PROVIDER is not specified. This enables e2e test(s)
(specifically StatefulSetBasic) to work.

Internal audit API
Forked from https://github.com/kubernetes/kubernetes/pull/45315
I pulled out only the internal audit API types and would like to merge this to unblock the audit implementation work while we figure out the versioned types and code generation.
I will continue to iterate on https://github.com/kubernetes/kubernetes/pull/45315, but lets get this internal type submitted.

Detect and prevent new vendor cycles
I see that we have added a dependency with a cyclic reference to
kubernetes. This makes life much harder, we should not do it. This
script should prevent any more offenders while we fix the existing one.

Copy internal types to metrics
Supersedes #45306.
#45306 removed the internal types and suggested whoever needs the internal types should define their own copy, and use the code-gen tools to generated the conversion functions. Per offline discussion with @DirectXMan12, we wanted to go that direction but it's not clear where to put the internal types yet. Hence, as a temporary solution, we decided copy the referred client-go/pkg/api types into metrics api to avoid the dependency.
The commit "remove need of registry from custom_metrics/client.go" is similar to what I did to the fake client in an earlier PR. Let me know if you want to put the commit in another PR.

Enable shared PID namespace by default for docker pods
**What this PR does / why we need it**: This PR enables PID namespace sharing for docker pods by default, bringing the behavior of docker in line with the other CRI runtimes when used with docker >= 1.13.1.

**Special notes for your reviewer**: cc @dchen1107 @yujuhong
**Release note**:
```release-note
Kubernetes now shares a single PID namespace among all containers in a pod when running with docker >= 1.13.1. This means processes can now signal processes in other containers in a pod, but it also means that the `kubectl exec {pod} kill 1` pattern will cause the pod to be restarted rather than a single container.
