Patrick Ohly 8c0865d881 Generate go.work files 
This creates go.work and enables Go Workspaces.  This is a file that
includes info on k/k and all the staging modules.

This depends on go 1.22 and setting FORCE_HOST_GO=true (for kube
scripts, which try to be hermetic).

Make this part of the normal update/verify sequence.

The top-level go.work file contains no replace statements. Instead, the
replace statements in the individual go.mod files are used. For this to
work, replace statements in the individual go.mod files have to be
consistent.

hack/tools has different dependencies and can't be in the main
workspace, so this adds a go.work just for that.  Without this, go tries
to consider all deps in all modules and pick one that works for all.
This is problematic because there are so many of them that it is
difficult to manage.

Likewise for k8s.io/code-generator/examples and
k8s.io/kms/internal/plugins/_mock - add trivial go.work files.

For example k/k depends on an older version of a lib that gloangci-lint
needs (transitively) and it breaks.

This also updates vendor (needed to make go happy), and removes
vendor'ed symlinks.  This breaks a LOT of our build tools, which will be
fixed subsequently.

Result: `go` commands work across modules:

Before:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api/core/v1

$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api

$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
main module (k8s.io/kubernetes) does not contain package k8s.io/kubernetes/staging/src/k8s.io/api
```

After:
```
$ go list ./pkg/proxy/iptables/ ./staging/src/k8s.io/api/core/v1/
k8s.io/kubernetes/pkg/proxy/iptables
k8s.io/api/core/v1

$ go build ./pkg/proxy/iptables/ ./staging/src/k8s.io/api

$ go test ./pkg/proxy/iptables/ ./staging/src/k8s.io/api
ok  	k8s.io/kubernetes/pkg/proxy/iptables	0.360s
ok  	k8s.io/api	2.302s
```

Result: `make` fails:

```

Again, this requires go 1.22 (e.g. gotip), as go 1.21.x does not have
`go work vendor` support.

Kube-controller-manager

Purpose

This library contains code to expose kube-controller-manager API.

Compatibility

There are NO compatibility guarantees for this repository, yet. It is in direct support of Kubernetes, so branches will track Kubernetes and be compatible with that repo. As we more cleanly separate the layers, we will review the compatibility guarantee. We have a goal to make this easier to use in the future.

Where does it come from?

kube-controller-manager is synced from https://github.com/kubernetes/kubernetes/blob/master/staging/src/k8s.io/kube-controller-manager. Code changes are made in that location, merged into k8s.io/kubernetes and later synced here.

Things you should NOT do

  1. Directly modify any files under pkg in this repo. Those are driven from k8s.io/kubernetes/staging/src/k8s.io/kube-controller-manager.
  2. Expect compatibility. This repo is changing quickly in direct support of Kubernetes and the kube-controller-manager API.
