Dynamic webhook admission control plugin
Unit tests pass.
Needs plumbing:
* [ ] service resolver (depends on @wfender PR)
* [x] client cert (depends on ????)
* [ ] hook source (depends on @caesarxuchao PR)
Also at least one thing will need to be renamed after Chao's PR merges.
```release-note
Allow remote admission controllers to be dynamically added and removed by administrators. External admission controllers make an HTTP POST containing details of the requested action which the service can approve or reject.

move labels to components which own the APIs
During the apimachinery split in 1.6, we accidentally moved several label APIs into apimachinery. They don't belong there, since the individual APIs are not general machinery concerns, but instead are the concern of particular components: most commonly the kubelet. This pull moves the labels into their owning components and out of API machinery.

Log out from multiple target portals when using iscsi storage plugin
**What this PR does / why we need it**:
When using iscsi storage with multiple target portal (TP) addresses
and multipathing the volume manager logs on to the IQN for all
portal addresses, but when a pod gets destroyed the volume manager
only logs out for the primary TP and sessions for another TPs are
always remained.
This patch adds mount points for all TPs, and then log out from all
TPs when a pod is destroyed. If a TP is referred from another pods,
the connection will be remained as usual.

Event aggregation: include latest event message in aggregate event
**What this PR does / why we need it**:
This changes the event aggregation behavior so that, when multiple events are deduplicated, the aggregated event includes the message of the latest related event.
This fixes an issue where the original event expires due to TTL, and the aggregate event doesn't contain any useful message.

Rotate kubelet client certificate.
Changes the kubelet so it bootstraps off the cert/key specified in the
config file and uses those to request new cert/key pairs from the
Certificate Signing Request API, as well as rotating client certificates
when they approach expiration.
Default behavior is for client certificate rotation to be disabled. If enabled
using a command line flag, the kubelet exits each time the certificate is
rotated. I tried to use `GetCertificate` in [tls.Config](https://golang.org/pkg/crypto/tls/#Config) but it is only called
on the server side of connections. Then I tried `GetClientCertificate`,
but it is new in 1.8.
**Release note**
```release-note
With --feature-gates=RotateKubeletClientCertificate=true set, the kubelet will
request a client 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.

Add support for creating resources that are not immediately visible to
naive clients, but must first be initialized by one or more privileged
cluster agents. These controllers can mark the object as initialized,
allowing others to see them.
Permission to override initialization defaults or modify an initializing
object is limited per resource to a virtual subresource "RESOURCE/initialize"
via RBAC.
Initialization is currently alpha.

Add jregan to OWNERS for kubectl isolation work.
The kubectl decoupling project (#598) requires many BUILD edits.
Even relatively simple PR's involve many OWNER files, e.g. #46317 involves five.
We plan to script-generate some PRs, and those may involve _hundreds_ of BUILD files.
This project will take many PRs, and collecting all approvals for each will be very time consuming.

[Flaky PR Test] Fix summary test
fixes issue: #46797
As we can see in the [example failure build log](https://storage.googleapis.com/kubernetes-jenkins/logs/ci-kubernetes-node-kubelet/4319/build-log.txt), the summary containers are pinging google 100s of times a second. This causes the summary container to be killed occasionally, and fail the test. The summary containers are only supposed to ping every 10 seconds according to the current test. As it turns out, we were missing a semicolon, and were not sleeping between pings. For background, we ping google to generate network traffic, so that the summary test can validate network metrics.
This PR adds the semicolon to make the container sleep between calls, and decreases the sleep time from 10 seconds to 1 second, as 1 call / 10 seconds did not produce enough activity.

Add a server side Get operation
Implement proposal kubernetes/community#363
```release-note
The Kubernetes API supports retrieving tabular output for API resources via a new mime-type `application/json;as=Table;v=v1alpha1;g=meta.k8s.io`. The returned object (if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`.
