Added script used to create PV and PVC

Storage-setup.sh is a script to launch a Persistent Volume mounting
from an NFS server on Kubernetes and have a Persistent Volume Claim
attach itself to it. This is needed to add persistent storage to Jenkins
slaves and build containers themselves. Script makes it so you can pass
a few variables and have the mount setup quickly.
