Recognize br-ex, br-int and br-tun as bridge interfaces
In the openstack dvr configuration scenario, bridges would be created on compute and network nodes called br-tun, br-ex, br-int and br-vlan. Unfortunately foreman does not recognize these devices as bridges, since the regex pattern matches only "br" + number (for that case).
This brings the unfortunate side effect, that the interfaces on which this bridges are created might vanish, because facter might report these with the same mac as the interfaces they were created on.
As this bridge naming pattern is quasi standard for some specific openstack configurations, it would be great if foreman would accept the "br-(\w)" pattern.
Implementation change would be required here:
