[Bug 1569974] [NEW] networking fallback should ignore bridges

[Scott Moser]

Public bug reported:

Serge pointed me at an an issue with cloud-init's fallback networking.
It will consider bridges as possible devices to dhcp on.
Since these bridges are configured only by things like lxd (not /etc/network/interfaces) they're not going to be good devices to 'dhcp' on and get a fallback networking configuration.

My short solution is to just ignore bridge devices when searching.
