Sample script to deploy K8S cluster won't work on Azure as they use temporary /mnt #609

Hi, This is about sql-server-samples/samples/features/sql-big-data-cluster/deployment/kubeadm/ubuntu/

Script relies on volumes created in /mnt (namely create /mnt/local-storage/vol1.... /mnt/local-storage/vol25). But /mnt in AzureVM is temporary storage, so it will work but everything will be gone after VM restart.

root@xxx:/mnt# pwd
/mnt
root@xxx:/mnt# ll

FYI i've successfully deployed BDC over Azure VMs using modified scripts hosted here temp_repo

It's a simple removal of /mnt/ part of path so that all volumes are at /local-storage (and therefore on C: drive).
