docs: def set_power_configuration(policy=None, delayType=None, delayValue=None):
      '''
      Sets the power configuration on the device. This is only available for some
      C-Series servers.
  
      .. versionadded:: 2019.2.0
  
      Args:
          policy(str): The action to be taken when chassis power is restored after
          an unexpected power loss. This can be one of the following:
  
              reset: The server is allowed to boot up normally when power is
              restored. The server can restart immediately or, optionally, after a
              fixed or random delay.
  
              stay-off: The server remains off until it is manually restarted.
  
              last-state: The server restarts and the system attempts to restore
              any processes that were running before power was lost.
  
          delayType(str): If the selected policy is reset, the restart can be
          delayed with this option. This can be one of the following:
  
              fixed: The server restarts after a fixed delay.
  
              random: The server restarts after a random delay.
  
          delayValue(int): If a fixed delay is selected, once chassis power is
          restored and the Cisco IMC has finished rebooting, the system waits for
          the specified number of seconds before restarting the server. Enter an
          integer between 0 and 240.
  
      CLI Example:

          salt '*' cimc.set_power_configuration stay-off
  
          salt '*' cimc.set_power_configuration reset fixed 0
