Feature cluster app install path refactoring
Change the structure to support multiple version of matlab. Introduce new location to install cluster shared apps and modulefiles following the structure below:
/export: application related that should be shared across the cluster
/export/eb: applications installed by EasyBuild
/export/apps/{app_name}/{version}: applications not installed by EasyBuild
/export/modulefiles/{app_name}/{version}: module files for applications not installed by EadyBuild
