The generation of zz_generated.deepcopy.go is broken

[tsaarni]

The exec in the following lines prevents controller-gen from running and re-generating the deepcopy files.

contour/hack/generate-crd-deepcopy.sh

Lines 45 to 46 in d05f43a

	exec echo "controller-gen version: "
	exec go run sigs.k8s.io/controller-tools/cmd/controller-gen --version

The files api/projectcontour/*/zz_generated.deepcopy.go are not being updated to reflect API changes, leading to compilation errors and potentially other issues.
