BUG-8665 32K Issue - Maximum of folder in shared/sites/files IMPROVEMENT

- No se modificaba la estructura porque no se tenia seteado la variable ENVIRONMENT_SETTINGS.
- Se modifico la funcion upgradeCasesDirectoryStructure para que cree la variable si no existe.
- Se movio la funcion upgradeCasesDirectoryStructure para que sea independiente al realizar el upgrade.
- se creo la funcion update-structure-directories para ejecutar por consola teniendo como parametro el workspace.
