Redfish Power Operation
    [Documentation]  Do Redfish host power operation.
    [Arguments]      ${reset_type}
    # Description of arguments:
    # reset_type     Type of power operation.
    #                (e.g. On/ForceOff/GracefulRestart/GracefulShutdown)

    # Example:
    # "Actions": {
    # "#ComputerSystem.Reset": {
    #  "ResetType@Redfish.AllowableValues": [
    #    "On",
    #    "ForceOff",
    #    "GracefulRestart",
    #    "GracefulShutdown"
    #  ],
    #  "target": "/redfish/v1/Systems/system/Actions/ComputerSystem.Reset"
    #  }
    # }

    Redfish.Login
    ${target}=  redfish_utils.Get Target Actions  /redfish/v1/Systems/system/  ComputerSystem.Reset
    ${payload}=  Create Dictionary  ResetType=${reset_type}
    ${resp}=  Redfish.Post  ${target}  body=&{payload}
    Redfish.Logout

    ${target}=  redfish_utils.Get Target Actions  /redfish/v1/Managers/bmc/  Manager.Reset
    ${payload}=  Create Dictionary  ResetType=GracefulRestart
    ${resp}=  Redfish.Post  ${target}  body=&{payload}
