Hi @gais-ameer-rh. 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.

Thanks Gais.

Overall looks good. There's a few small changes I would like.

There are two duplicate commits (b5f6ccc and 2436c3a) with very similar messages. Please use git squash so turn them into one commit.
