PVC storage claims for SSD in GCP issues

[salaboy]

We need to figure out a clean up strategy for PVCs in GCP.
After running install script several times we hit the quota for PVCs in GCP

  Warning    ProvisioningFailed  77s (x12 over 11m)  persistentvolume-controller  Failed to provision volume with StorageClass "zeebe-regional": googleapi: Error 403: QUOTA_EXCEEDED - Quota 'SSD_TOTAL_GB' exceeded.  Limit: 100.0 in region us-west1.

We need to provide a clean up script (uninstall) to make sure that resources are released.

Further investigation highlighted that there is a problem in some Kubernetes versions where the pods and deployments are not removed even if the PVC are removed.
