Add ResetActionInfo for ResetType

OCP mandate the ResetActionInfo for convey the
parameter requirements and allowable values on
parameters for actions. So add ResetActionInfo
uri for below URI's.
/redfish/v1/Systems/system/ResetActionInfo
/redfish/v1/Managers/bmc/ResetActionInfo
/redfish/v1/Chassis/<id>/ResetActionInfo

Tested:
 - All action uri's show correct @Redfish.ActionInfo
   "Actions": {
    "#ComputerSystem.Reset": {
      "@Redfish.ActionInfo": "/redfish/v1/Systems/system/ResetActionInfo",
      "target": "/redfish/v1/Systems/system/Actions/ComputerSystem.Reset"
    }
  }

 - All /ResetActionInfo uri's show correct allowable
   values.
   {
    "@odata.id": "/redfish/v1/Systems/system/ResetActionInfo",
    "@odata.type": "#ActionInfo.v1_1_2.ActionInfo",
    "Id": "ResetActionInfo",
    "Name": "Reset Action Info",
    "Parameters": {
     "AllowableValues": [
      "On",
      "ForceOff",
      "ForceOn",
      "ForceRestart",
      "GracefulRestart",
      "GracefulShutdown",
      "PowerCycle",
      "Nmi"
    ],
    "DataType": "String",
    "Name": "ResetType",
    "Required": true
   }
  }

 - Ran redfish validator and its successful.
