make ore openstack gc clean up SSH keypairs

[dustymabe]

We've been bumping up into quota limits for SSH keypairs in VexxHost (our openstack provider for kola testing) and I didn't quite understand why because the web interface doesn't show me any keypairs so I didn't think any existed. However checking via the CLI I see a lot. So somehow sometimes keypairs aren't getting cleaned up. We could/should make our GC that we run in the pipeline just detect when stale keypairs exist and delete them too. I think we can just filter by keypairs with a name starting with kola- and created before a certain time:

$ openstack keypair show kola-09efd27b-7512-4a51-b795-24bb82eafdf2
+-------------+-------------------------------------------------+

| created_at  | 2023-08-01T03:21:24.000000                      |

| id          | kola-09efd27b-7512-4a51-b795-24bb82eafdf2       |
| is_deleted  | False                                           |
| name        | kola-09efd27b-7512-4a51-b795-24bb82eafdf2       |
| private_key | None                                            |
| type        | ssh                                             |
| user_id     | c6dffb4547d04cd2bd7ed672c02e2f6d                |
+-------------+-------------------------------------------------+

For now I unblocked things by running:

$ export OS_REGION_NAME="ca-ymq-1"                                    
$ openstack keypair list -f json | jq -r .[].Name | grep kola | xargs openstack keypair delete

I've been looking at how to implement this and I'm wondering if the kola-openstack job runs garbage collection at all right now? Is it run by default or do we have to specify? I see that in kola-gcp and kola-azure we are running the garbage collection stages manually, but not in kola-openstack. I can open a PR to run GC in openstack if it needs to be specified manually (i'm assuming it does)

In my mind I had cross linked this ticket back here when I opened it, but in practice that didn't happen. See

Ah, perfect. I'll work on that.
