WIP: fix(openstack): determine ports to delete based on tags

[ederst]

This will determine the ports to delete when deleting an InstanceGroup in OpenStack based on the tags, rather than comparing the prefix of the name of the port to a pattern.

The current approach for deleting ports associated with an InstanceGroup in OpenStack can be problematic.

For example, when creating an InstanceGroup called worker and another one called worker-2. Some of the ports kOps creates for those groups will look like this:

• port-worker-2-1-<clusterName>
• port-worker-2-2-<clusterName>
• port-worker-1-<clusterName>
• port-worker-2-<clusterName>
• port-worker-20-<clusterName>

Deleting the worker-2 IG will ultimately delete all the ports prefixed with port-worker-2, which means that kOps will also delete ports of the worker IG.

Hi @ederst. Thanks for your PR.

I'm waiting for a kubernetes 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.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
