Getting started script will not work if /data already exists

[vladimirvivien]

When the /data directory already exists and the run.sh script is executed, it skips creating the crunch-pvc resource. This in turn will cause the pgo create cluster testcluster to fail when attempting to attach /pgdata

kubectl get pods

Based on kubelet logs, the crunchy-pvc is not found:

thanks Vladimir, I've made a change to that script that should resolve this one.
