Nodes can't connect to rabbitmq on Fuel node if you use non eth0 as admin interface

[Aleksandr Didenko]

In nailgun::host we declare nailgun::iptables class without parameters. So admin_iface parameter of nailgun::iptables defaults to eth0 thus blocking rabbitmq ports from real Fuel admin network:

 18 9 536 ACCEPT tcp -- eth0 * 0.0.0.0/0 0.0.0.0/0 multiport ports 4369,5672,15672,61613 /* 040 rabbitmq_admin */

How to reproduce: deploy Fuel with admin network which is not on eth0, bootstrap node, try to deploy any role on it (or run "mco ping" on Fuel node, it won't see anybody except master).

This seems to still be a problem in 7.

User had admin interface on eth1 which is in the rules but connections were still being blocked.
