Fix issues with metallb on OKD

[eb4x]

Slightly different approach, just get the latest (v0.14.2) release, patch what needs to be patched and and apply with -k for kustomize. No need to wait for operatorhub.io or the deployment to fail before patching.

The deployment for webhook-server wants to pull
quay.io/metallb/controller:main for the webhook-server. Which seems to be a moving target, and recently was expecting to find an additional CRD for service.BGPStatuses. So we pin the controller to v0.14.5, which is what the other controller images are pinned to in this release.

Hi @eb4x. Thanks for your PR.

I'm waiting for a openstack-k8s-operators member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
