Allow NetworkPolicy.spec updates
ValidateNetworkPolicyUpdate currently prohibits changes to `spec` in an existing NetworkPolicy. We were going to fix this for 1.7 but I forgot to submit this PR after the main PR merged. Too late for 1.7? @thockin @caseydavenport @cmluciano
This only changes networking.NetworkPolicy validation at the moment... Should I change extensions.NetworkPolicy validation too?
Fixes#35911
We should add a test to the e2e NetworkPolicy test for this too if this is going to merge.
**Release note**:
```release-note
As part of the NetworkPolicy "v1" changes, it is also now
possible to update the spec field of an existing
NetworkPolicy. (Previously you had to delete and recreate a
NetworkPolicy if you wanted to change it.)

Move the kubelet certificate management code into a single package
Code is very similar and belongs together. Will allow future cert callers to potentially make this more generic, as well as to make it easier reuse code elsewhere.

Add Google cloudkms dependency, add cloudkms service to GCE cloud provider
Required to introduce a Google KMS based envelope encryption, which shall allow encrypting secrets at rest using KEK-DEK scheme.
The above requires KMS API to create/delete KeyRings and CryptoKeys, and Encrypt/Decrypt data.
Should target release 1.8

Update: It appears that Godep only allows dependencies which are in use. We may have to modify this PR to include some Google KMS code.

Provide a way to setup the limit NO files for rkt Pods
**What this PR does / why we need it**:
This PR allows to customize the Systemd unit files for rkt pods.
We start with the `systemd-unit-option.rkt.kubernetes.io/LimitNOFILE` to allows to run workloads like etcd, ES in kubernetes with rkt.
**Special notes for your reviewer**:
Once again, I followed @yifan-gu guidelines.
I made a basic check over the values given inside the `systemd-unit-option.rkt.kubernetes.io/LimitNOFILE` (integer and > 0).
If this check fails: I simply ignore the field.
The other implementation would be to fail the whole SetUpPod.
We discussed using a key like `rkt.kubernetes.io/systemd-unit-option/LimitNOFILE` but the validation only allows a single `/` in this field:
```The Deployment "tiller" is invalid: spec.template.annotations: Invalid value: "rkt.kubernetes.io/systemd-unit-option/LimitNOFILE": a qualified name must consist of alphanumeric characters, '-', '_' or '.', and must start and end with an alphanumeric character (e.g. 'MyName', or 'my.name', or '123-abc', regex used for validation is '([A-Za-z0-9][-A-Za-z0-9_.]*)?[A-Za-z0-9]') with an optional DNS subdomain prefix and '/' (e.g. 'example.com/MyName')```

```release-note

Fix kubectl describe for pods with controllerRef
**What this PR does / why we need it**:
kubectl describe doesn't take controllerRef into consideration, resulting confusing result. e.g. if we have two replicaset with the same selector, one with 1 replica and the other 2 replicase, then both replicaset will show 3 running pods.
```sh
$ kubectl describe rs replicaset-2

Refactor podListEqual()
**What this PR does / why we need it**:
To solve the problem:
this is not correct if there are duplicate pods in the list.
for example: podListEqual([a, a, b], [a, b, b]) will return true
**Special notes for your reviewer**:
the original method is O(N^2), while current method is 3* O(N).
I think it is much better.

allow a deletestrategy to opt-out of GC
Not all resources should be GC-able and we implemented an ignore list to handle this, but at the storage layer they could still set finalizers, they just hung in a stuck state forever. This updates the strategy to allow a resource to indicate that they shouldn't be GCed.
