client-gen API not generated correctly

[jcaamano]

It has two issues, related to
kubernetes/code-generator#167
kubernetes/kubernetes#125162

Issue 1

If fails while consuming in downstrean projects due to go tooling not tolerating links on imports:

frr-k8s/pkg/client/clientset/versioned/scheme/register.go

Line 8 in 8787023

corev1beta1 "github.com/metallb/frr-k8s/core/v1beta1"

does not work while

corev1beta1 "github.com/metallb/frr-k8s/api/v1beta1"

would work

Fixed by adding

find pkg/client/ -type f -name "*.go" -print0 | xargs -0 sed -i 's|"github.com\/metallb\/frr-k8s\/core\/|"github.com/metallb/frr-k8s/api/|g'

at the end of update-codegen.sh

Issue 2

The generated client uses api instead of apis in the URL path and requests fail.

Fixed by adding

find pkg/client/ -type f -name "*.go" -print0 | xargs -0 sed -i  's|config.APIPath = "/api"|config.APIPath = "/apis"|g'

at the end of update-codegen.sh
