Fix conflict about getPortByIp
**What this PR does / why we need it**:
Currently getPortByIp() get port of instance only based on IP.
If there are two instances in diffent network and the CIDR of
their subnet are same, getPortByIp() will be conflict.
My PR gets port based on IP and Name of instance.

Manage BUILD files using gazelle + kazel
**What this PR does / why we need it**: uses the upstream `gazelle` tool to manage go rules in BUILD files.
This is needed to support Bazel builds on Mac OS and Bazel cross compilation in general.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#47558
**Special notes for your reviewer**:
It's probably easiest to review this commit-by-commit:
* bump to latest `rules_go` (for recent `cgo_library` and `gazelle` improvements)
* update `kazel` with recent compatibility fixes (https://github.com/kubernetes/repo-infra/pull/28, https://github.com/kubernetes/repo-infra/pull/27), update `hack` scripts to download/build `gazelle`, and then run both `gazelle` and `kazel`. (Additionally make `gazelle` skip things it shouldn't touch.)
* run `hack/update-bazel.sh` to autogenerate everything
* remove the old `cgo_genrule` rules - these are now part of `go_library`
* remove the `automanaged` tags from all go rules - `gazelle` doesn't use them, and it prevents an old version of `kazel/gazel` from messing with the rules
* remove the `licenses()` rules from everywhere but `third_party/` - we don't need them, and `gazelle` won't add them on new `BUILD` files it generates.

Revert "Merge pull request #47353 from apelisse/http-cache"
Some issues were discovered with the caching merged in #47353:
* uses a disk-based cache that is not safe between processes (does not use atomic fs operations)
* writes get/list responses to disk that should not be cached (like `kubectl get secrets`)
* is vulnerable to partially written cache responses being used as responses to future requests
* breaks uses of the client transport that make use of websockets
* defaults to enabling the cache for any client builder using RecommendedConfigOverrideFlags or DefaultClientConfig which affects more components than just kubectl

Timeout and Max-in-flight don't report non-resource URLs correctly.
Unify error reporting for 429 and 504 to be correct for timeout and max in flight and eviction. Add better messages to eviction (removing a todo). Return the correct body content for timeouts (reason and code should be correct).
This potentially increases cardinality of 429, but because non-api urls may be under the max-inflight budget we need to report them somewhere (if something breaks and starts fetching API versions endlessly).
```release-note
The 504 timeout error was returning a JSON error body that indicated it was a 500. The body contents now correctly report a 500 error.

go-client: Use httpcache client for all requests, even though only openapi returns ETags for caching

This also adds a new command-line flag "cachedir" to specify where the cache should keep its file. It defaults to `$HOME/.kube/http-cache`.

**Special notes for your reviewer**:
Because this adds a bunch of dependencies, and removes a couple of files, I do recommend reading each commit individually.

Switch from package syscall to golang.org/x/sys/unix
**What this PR does / why we need it**:
The syscall package is locked down and the comment in https://github.com/golang/go/blob/master/src/syscall/syscall.go#L21-L24 advises to switch code to use the corresponding package from golang.org/x/sys. This PR does so and replaces usage of package syscall with package golang.org/x/sys/unix where applicable. This will also allow to get updates and fixes
without having to use a new go version.
In order to get the latest functionality, golang.org/x/sys/ is re-vendored. This also allows to use Eventfd() from this package instead of calling the eventfd() C function.
**Special notes for your reviewer**:
This follows previous works in other Go projects, see e.g. moby/moby#33399, cilium/cilium#588

Reintegrate aggregation support for OpenAPI
Reintegrating changes of #46734
Changes summary:
- Extracted all OpenAPI specs to new repo `kube-openapi`
- Make OpenAPI spec aggregator to copy and rename any non-requal model (even with documentation change only).
- Load specs when adding APIServices and retry on failure until successful spec retrieval or a 404.
- Assumes all Specs except aggregator's Spec are static
- A re-register of any APIService will result in updating the spec for that service (Suggestion for TPR: they should be registered to aggregator API Server, Open for discussion if any more changes needed for another PR.)

github.com/davecgh/go-spew/spew is set to the newest version, a bit
newer than required by testify. Updated from version 6 Nov 2015 to
27 Jun 2017.
github.com/stretchr/objx is not updated - testify uses version
from 27 May 2014 which is older than 28 Sep 2015 used now (latest
actually). In practice there is only a tiny difference - one method was
removed in new version.
