[cisco-aci-plugin] instances connected to the one of default networks fail with an error during launch

[Ruslan Khozinov]

Steps:
1. Deploy an env: 1 compute + 1 controller (with settings, that described in attached pics)
2. Go to dashboard (or to cli) and check default networks. In my case I have to networks:

root@node-7:~# neutron net-list -c name -c subnets
+-----------+-------------------------------------------------------+
| name | subnets |
+-----------+-------------------------------------------------------+
| net04_ext | f21d4556-3aea-40dc-bdc2-9358e5033687 10.109.1.0/24 |
| net04 | c89ac17a-c62d-4cb4-add5-4a31cfefff55 192.168.111.0/24 |
+-----------+-------------------------------------------------------+

3. Then need to launch 2 instances, connected to net04_ext and 2 instances, connected to net04

4. 2 instances, connected to net04_ext are not launched with the next error:

Fault

Message
No valid host was found.
