Add cos as an alias for gci in the upgrade script
This was causing some issues when upgrading from a GCI image. This is the same conversion happening in config-defaults.sh.
https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/logs/ci-kubernetes-e2e-gce-stable2-stable1-upgrade-cluster-new/205
The node image was being left at COS, and when we went to build the kube-env, we only check against "gci". This caused us to not fully construct the environment for nodes and then they couldn't fully come up after an upgrade.
I've already fixed the CI test suites to explicitly specify "gci", but this auto-detection logic should be fixed too.

Remove cloud provider rackspace
**What this PR does / why we need it**:
For now, we have to implement functions in both `rackspace` and `openstack` packages if we want to add function for cinder, for example [resize for cinder](https://github.com/kubernetes/kubernetes/pull/51498). Since openstack has implemented all the functions rackspace has, and rackspace is considered deprecated for a long time, [rackspace deprecated](https://github.com/rackspace/gophercloud/issues/592) ,
after talking with @mikedanese and @jamiehannaford offline , i sent this PR to remove `rackspace` in favor of `openstack`
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#52854
**Special notes for your reviewer**:
**Release note**:
```release-note
The Rackspace cloud provider has been removed after a long deprecation period. It was deprecated because it duplicates a lot of the OpenStack logic and can no longer be maintained. Please use the OpenStack cloud provider instead.
