Redfish Code Update : New property for ApplyTime

Defining a new property which can control when to apply the
newly uploaded software image. This maps to the ApplyTime property defined
in the UpdateService redfish schema:
http://redfish.dmtf.org/schemas/v1/UpdateService.v1_4_0.json
        "ApplyTime": {
            "enum": [
                "Immediate",
                "OnReset",
                "AtMaintenanceWindowStart",
                "InMaintenanceWindowOnReset"
            ],

As of now the values "Immediate" and "OnReset" are supported and the value
can be supplied through HttpPushUriApplyTime object.
