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

f2e23afcf1 Adds filtering of hosts to DialContexts.
The provided DialContext wraps existing clients' DialContext in an attempt to
preserve any existing timeout configuration. In some cases, we may replace
infinite timeouts with golang defaults.

- scaleio: tcp connect/keepalive values changed from 0/15 to 30/30
- storageos: no change

a46e1f0613 kube-proxy ShouldSkipService takes only one argument
instead of receiving the service name and namespace we
can obtain it from the service object directly.

kube-proxy filter Load Balancer Status ingress
kube-proxy, if is configured with an IP family, filters out the
incorrect IP version of the services.

This commit fix a bug caused by not filtering out the IPs in the
LoadBalancer Status Ingress field.

use split host port func instead trim specific character

add unit test for metrics and healthz bind address

recover import package

refactor set default kube proxy configuration

fix ipv4 condition

fix set default port condition

rewrite call function occasion to reduce error

set ipv6 default value

move get GetBindAddressHostPort to util

use one func to handle deprecated series

update bazel

define address type

return earlier in the error case

refactor set default kube proxy configuration logic

recover import package

preserve some of the original comments

add get default address func

add append port if needed unit test

rewrite unit test for deprecated flags

remove unused codes
