Update to sigs.k8s.io/controller-runtime@v0.15.0

[prometherion]

Proposal

At the current state (1179eaa) the controller-runtime dependency is pinned to v0.15.0-alpha.0.

Last week, the latest stable release of controller-runtime was officially released as v0.15.0.

Some breaking changes have been introduced, such as the webhook.Validator interface: as a developer who is importing the keda code-base, and who has built its own operator based on v0.15.0, I'm blocked due to mismatching signature.

# github.com/kedacore/keda/v2/apis/keda/v1alpha1
../../../go/pkg/mod/github.com/kedacore/keda/v2@v2.10.1/apis/keda/v1alpha1/scaledobject_webhook.go:53:27: cannot use &ScaledObject{} (value of type *ScaledObject) as type admission.Validator in variable declaration:
	*ScaledObject does not implement admission.Validator (wrong type for ValidateCreate method)
		have ValidateCreate() error
		want ValidateCreate() (warnings admission.Warnings, err error)

Use-Case

By developing an Operator with controller-runtime@v0.15.0 I should be able to import the keda code base without any downside.

Is this a feature you are interested in implementing yourself?

Maybe

Anything else?

Hi,
This makes sense totally, and it was in my TODOs indeed. Are you willing to bump it from your side and open a PR?
