* updating Harvester addon configuration docs to represent the yaml more accurately
* updating the Harvester addon docs to display information surrounding
  the naming that is displayed in the UI to the end user in contrast to
  the naming that is displayed via kubectl commands to the cluster that
  demonstrate the "chartName"
