Subject: live: add boot entries into /refresh payload

Add 'efi' key into the refresh payload. The value for that key
has the following structure:

'efi': {
  'entries': [
    {
      "order": 0,
      "name": "Boot0000",
      "active": false,
      "description": "grub"
    },
    {
      "order": 1,
      "name": "Boot0001",
      "active": true,
      "description": "UEFI: PXE IP4 Realtek PCIe GBE Family Controller"
    }
  ]
}

If the client is not a EFI system it won't add the 'efi' field.
If an entry is not in the boot order it won't have the 'order' field.
