Added support for checking on the health status of an NVDIMM

* The check for the health status piggy backs off the current
  NVDIMM operation interface.
* Added the method doNvDimmCheckHealthStatus to perform the
  health check status of the individual NVDIMMs.
* Added wrapper methods nvDimmCheckHealthStatusOnSystem and
  nvdimmCheckHealthStatus that call the doNvDimmCheckHealthStatus
* Added an interface in the runtime commands to call make
  the check health status call.
