controller-runtime version 0.14.X incompatible with client-go 0.27

[Huang-Wei]

Usually the first step after releasing is to bump the k8s deps in master branch. But in local testing, it turns out a change in client-go caused all controller-runtime 0.14.X versions incompatible.

• issue Get error go/tools/cache".ResourceEventHandlerRegistration (missing method HasSynced) operator-framework/operator-sdk#6396 has been reported elsewhere
• to be compatible with k8s v1.27, we need to vendor a controller-runtime version (v0.15.0+) that contains the fix: 🐛 Add cross-version compatibility with client-go 1.27 controller-runtime#2223

[Huang-Wei]

when bumping controller-runtime, I hit 2 issues:

One is:

⇒  go mod tidy
sigs.k8s.io/scheduler-plugins/cmd/scheduler imports
	k8s.io/kubernetes/cmd/kube-scheduler/app imports
	k8s.io/apiserver/pkg/server imports
	k8s.io/apiserver/pkg/registry/generic imports
	k8s.io/apiserver/pkg/storage/storagebackend/factory imports
	go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc tested by
	go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc.test imports
	google.golang.org/grpc/interop imports
	golang.org/x/oauth2/google imports
	cloud.google.com/go/compute/metadata: ambiguous import: found package cloud.google.com/go/compute/metadata in multiple modules:
	cloud.google.com/go v0.97.0 (/Users/weih/go/pkg/mod/cloud.google.com/go@v0.97.0/compute/metadata)
	cloud.google.com/go/compute/metadata v0.2.0 (/Users/weih/go/pkg/mod/cloud.google.com/go/compute/metadata@v0.2.0)

This can be fixed by go get cloud.google.com/go/compute/metadata first and then go mod tidy.

The next one is:

⇒  go test ./cmd/...
# sigs.k8s.io/scheduler-plugins/pkg/controllers
pkg/controllers/elasticquota_controller.go:176:12: source.Kind (value of type func(cache "sigs.k8s.io/controller-runtime/pkg/cache".Cache, object client.Object) source.SyncingSource) is not a type

working on it...

the second one seems familiar to me, I would help to fix it before the other migrations if you have not yet fixed it. @Huang-Wei

[Huang-Wei]

Thanks @zwpaper . I think I fixed the second one as well. But somehow there is another UT failure.

If you'd like to take a stab, I will upload my (temporary) PR, and then you take over from there. so you don't need to start from scratch, WDYT?
