In networks are created without all fields, preventing update

[Alexandr Kostrikov]

There is a network in nailgun, created with fuel-qa multiple networks

dockerctl shell postgres su - postgres -c 'psql -d nailgun'
psql (9.3.5)
Type "help" for help.

nailgun=# select * from network_groups where id = 7;
 id | name | release | vlan_start | cidr | gateway | meta | group_id
----+------------+---------+------------+---------------+---------+----------------------------------------------+----------
  7 | management | 2 | 101 | 10.250.2.0/24 | | {"ip_range": ["10.250.2.1", "10.250.2.254"]} | 2
(1 row)

But update checks for notation in meta.
https://github.com/stackforge/fuel-web/blob/master/nailgun/nailgun/objects/network_group.py#L116

So, this produces a conflict.

Should it be fixed in fuel-qa or more strict validation should be also applied in nailgun?
