Switch a hubPlatform firmware to a Luup one

User can switch hub's firmware to a Luup firmware one if it's desired/needed.

hub.firmware.luup.switch

call

{
    "id": "_ID_",
    "method": "hub.firmware.luup.switch",
    "params": {}
}

At this moment, after a hub started to perfrom switching there's no way to know the progres, so errors get reported only about inpossibility of operation (checked before switching has been started).

{
    "error": null,
    "id": "_ID_",
    "result": {}
}
