There is no easy way today to disable the webhook server. I think we should improve this.

I think there are use cases where no webhook server (and accordingly no conversion & admission webhooks) is needed.

In my current case I just wanted to run the reconcilers of a controller for debugging purposes.

The current situation is that if no WebhookServer is provided via Options.WebhookServer the manager will instantiate a default server.

The default server itself also has no way to disable it (e.g. via an explicit flag or setting the port to -1). For comparison the metrics server is disabled if BindAddress is set to 0.

The only way I found to disable the metrics server is to configure a "no-op" webhook server via options. Would be nice if that would be easier.
