It should be a bit easier to setup webhook handlers without a manger

[DirectXMan12]

It's currently intended to be possible to set up webhook handlers w/o a manager (e.g. in your own HTTP mux, in a separate binary that doesn't need to have a REST config, etc), but it's not easy due to the dependency injection setup from the manager.

We should have a helper to make the dependencies more explicit, and to make this a bit easier.

I think there's two thing to care about here:

• Can we set up a "normal" server without a manager / cluster connection information?
• Can we attach controller-runtime webhooks to an existing arbitrary Go HTTP server (http.ServeMux) that's managing its own serving (i.e. not a webhook.Server)
