Currently we hard-code default values of XtremIO driver parameters but these default values are same as the service defaults. This change replaces hard-coded defaults by service defaults. This allows us to avoid maintaining own default values in puppet modules, and reduces amount of maintenance effort. Change-Id: I3d085b2b8441153c356062bd22ac2521950bff35
