New scratch filesystem for Euler

Introduction

Up to now, the personal scratch directory (/cluster/scratch/$USER) and the work storage shares (/cluster/work/) were hosted on the same Lustre file system. By adding a new Lustre filesystem for the personal scratch directories, these two types of storage are now separated.

Migration of users personal scratch directories

The migration of the users scratch directory is transparent and the new scratch file system will have the same paths as the old one. Therefore no action needs to be taken on the users side.
