fuelmenu fails to run due to usage of "value" field in UI scheme

[Vladimir Kozhukalov]

Steps to reproduce:
1. Launch fuelmenu with cmd: `fuelmenu`

Expected behavior:
fuelmenu launched

Actual result:
[root@fuel ~]# fuelmenu
Traceback (most recent call last):
  File "/usr/bin/fuelmenu", line 9, in <module>

This patch uses old defaults field names while they were renamed recently.
