Verify kubernetes objects with DryRun #3425

Describe the feature
In Kubernetes 1.13 a dry-run feature was added to allow validating an object without instantiating it.
Our architecture has a mutating webhook as well as a controller to reconcile events. Today our webhook validations are not great at catching problems with kubernetes shapes such as the corev1.Container shape. Any issues that get through our validation that fail kubernetes validations result in the controller unable to reconcile which is further along in the API call lifecycle and more difficult to debug.
This issue is to leverage the dry-run feature in our webhook to ensure kubernetes shapes we are passed are validated synchronously with the user's request. Since this will require Kubernetes 1.13 it is currently blocked on other reasons for us to move forward to requiring a higher version, but capturing this here for potential future Knative releases.
