docs: // ChangeContactModhattr creates a new "CHANGE_CONTACT_MODHATTR" Nagios command.
  //
  // This command changes the modified host attributes value for the specified contact.
  //
  // Modified attributes values are used by Nagios to determine which object properties should be retained across program
  // restarts.
  //
  // Thus, modifying the value of the attributes can affect data retention.
  //
  // This is an advanced option and should only be used by people who are intimately familiar with the data retention
  // logic in Nagios.
