dual stack services (#91824)
* api: structure change

* api: defaulting, conversion, and validation

* [FIX] validation: auto remove second ip/family when service changes to SingleStack

* [FIX] api: defaulting, conversion, and validation

* api-server: clusterIPs alloc, printers, storage and strategy

* [FIX] clusterIPs default on read

* alloc: auto remove second ip/family when service changes to SingleStack

* api-server: repair loop handling for clusterIPs

* api-server: force kubernetes default service into single stack

* api-server: tie dualstack feature flag with endpoint feature flag

* controller-manager: feature flag, endpoint, and endpointSlice controllers handling multi family service

* [FIX] controller-manager: feature flag, endpoint, and endpointSlicecontrollers handling multi family service

* kube-proxy: feature-flag, utils, proxier, and meta proxier

* [FIX] kubeproxy: call both proxier at the same time

* kubenet: remove forced pod IP sorting

* kubectl: modify describe to include ClusterIPs, IPFamilies, and IPFamilyPolicy

* e2e: fix tests that depends on IPFamily field AND add dual stack tests

* e2e: fix expected error message for ClusterIP immutability

* add integration tests for dualstack

the third phase of dual stack is a very complex change in the API,
basically it introduces Dual Stack services. Main changes are:

- It pluralizes the Service IPFamily field to IPFamilies,
and removes the singular field.
- It introduces a new field IPFamilyPolicyType that can take
3 values to express the "dual-stack(mad)ness" of the cluster:
SingleStack, PreferDualStack and RequireDualStack
- It pluralizes ClusterIP to ClusterIPs.

The goal is to add coverage to the services API operations,
taking into account the 6 different modes a cluster can have:

- single stack: IP4 or IPv6 (as of today)
- dual stack: IPv4 only, IPv6 only, IPv4 - IPv6, IPv6 - IPv4

* [FIX] add integration tests for dualstack

* generated data

* generated files

e46572ef4b Improve EndpointController's handling of headless services under dual-stack
EndpointController was accidentally requiring all headless services to
be IPv4-only in clusters with IPv6DualStack enabled.

This still leaves "legacy" (ie, IPFamily-less) headless services as
always IPv4-only because the controller doesn't currently have easy
access to the information that would allow it to fix that.
(EndpointSliceController had the same problem already, and still
does.) This can be fixed, if needed, by manually setting IPFamily,
and the proposed API for 1.20 will handle this situation better.

9fb6e2ef55 Fix Endpoint/EndpointSlice pod change detection
The endpoint controllers responded to Pod changes by trying to figure
out if the generated endpoint resource would change, rather than just
checking if the Pod had changed, but since the set of Pod fields that
need to be checked depend on the Service and Node as well, the code
ended up only checking for a subset of the changes it should have.

In particular, EndpointSliceController ended up only looking at IPv4
Pod IPs when processing Pod update events, so when a Pod went from
having no IP to having only an IPv6 IP, EndpointSliceController would
think it hadn't changed.

Setting Hostname from Pods on EndpointSlice to match Endpoints behavior.
This was an oversight in the initial EndpointSlice release. This update
will ensure that Endpoints and EndpointSlices use the same logic to set
the Hostname attribute.

Move from glog to klog
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
  * github.com/kubernetes/repo-infra
  * k8s.io/gengo/
  * k8s.io/kube-openapi/
  * github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

The patch removes ExternalID usage from node_controller

which returns the cloud provider ID as well.

e18e8ec3c0 Add context to all relevant cloud APIs
This adds context to all the relevant cloud provider interface signatures.
Callers of those APIs are currently satisfied using context.TODO().
There will be follow on PRs to push the context through the stack.
For an idea of the full scope of this change please look at PR #58532.

9187b343e1 Split the NodeController into lifecycle and ipam pieces.
Prepatory work fpr removing cloud provider dependency from node
controller running in Kube Controller Manager. Splitting the node
controller into its two major pieces life-cycle and CIDR/IP
management. Both pieces currently need the the cloud system to do their work.
Removing lifecycles dependency on cloud will be fixed ina followup PR.

Moved node scheduler code to live with node lifecycle controller.
Got the IPAM/Lifecycle split completed. Still need to rename pieces.
Made changes to the utils and tests so they would be in the appropriate
package.
Moved the node based ipam code to nodeipam.
Made the relevant tests pass.
Moved common node controller util code to nodeutil.
Removed unneeded pod informer sync from node ipam controller.
Fixed linter issues.
Factored in  feedback from @gmarek.
Factored in feedback from @mtaufen.
Undoing unneeded change.
