Set metrics storage for HCI

When deploy FR2 using HCI using ci framework:

./deploy-architecture.sh -e zuul_log_collection=true -e cifmw_nolog=false -e cifmw_run_tests=false

It first `kustomize_deploy/control-plane.yaml` gets deployed and
afterwards updates it `kustomize_deploy/nodeset-post-ceph.yaml`
which updates that telemetry section and sets:
~~~
    persistentVolumeClaim:
      resources:
        requests:
          storage: 20G
~~

~~~
$ oc get osctlplane -n openstack -w
NAME           STATUS   MESSAGE
controlplane   True     Setup complete
controlplane   True     Setup complete
controlplane   False    OpenStackControlPlane RabbitMQ in progress
controlplane   False    OpenStackControlPlane RabbitMQ error occured rabbitmq-notifications(Secret "cert-rabbitmq-notifications-svc" not found)
controlplane   False    OpenStackControlPlane Telemetry in progress
controlplane   False    OpenStackControlPlane Telemetry in progress
controlplane   False    OpenStackControlPlane Telemetry in progress
controlplane   False    OpenStackControlPlane Telemetry in progress
controlplane   False    OpenStackControlPlane Telemetry in progress
~~~

Since the initial deploy was with 10G and now switches to 20G (there
usually are no 20G local storage volumes), the ctlplane is stuck in
progress.

This updates the hci example to use 10G with local-storage storage
class to align with the initial setup.
