Subject: rest: add GET /efi

Add GET /efi request to obtain information about the client's
boot entries.

Field inside the /refresh payload
'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.

GET /efi resquest payload structure:
{
    'clients': ['10.141.10.21', '10.141.10.22']
}

GET /efi response's structure:
{
  'clients': [
    {
      'ip': '10.141.10.21',
      'entries': [
        {
          "order": 0,
          "name": "Boot0000",
          "active": false,
          "description": "grub"
        },
        {
          "order": 1,
          "name": "Boot0001",
          "active": true,
          "description": "UEFI: PXE IP4 Realtek PCIe GBE Family Controller"
        }
      ]
    },
    {
      'ip': '10.141.10.22',
      'entries': []
    }
  ]
}

The client with ip 10.141.10.22 is a BIOS system.

If an entry does not appear in the boot order it won't have the
'order' field.
