feat(hcp): Add Hosted Control Plane cluster stack for OpenStack

Add the HCP cluster stack (providers/openstack/hcp/) with three K8s
minor versions (1-33, 1-34, 1-35). Uses the teutonet
cluster-api-provider-hosted-control-plane instead of
KubeadmControlPlane — the control plane runs as pods in the management
cluster, only worker nodes are provisioned as OpenStack VMs.

Based on the origin/hcp branch, adapted to the per-minor-version
directory structure with stack.yaml and version-appropriate addon
pinning (CCM/CSI matched to K8s minor, Cilium 1.19.1).
