Support multiple network bridges per container

[gopi-ar]

If I add an additional lines to the container's config as described here http://www.boxtricks.com/multiple-network-interfaces-lxc-container/, LWP throws an Internal Server Error.

Multiple bridges are very useful when there's a br0 for public IPs (for example), and lxcbr0 for local IPs.

We should handle these type of config files without throwing an error.

Hello @gopi-ar, this could be a great feature but we should deal with ConfigParser limitation and I don't have any idea how to deal with it.

@emibcn suggest some idea here lxc-webpanel/LXC-Web-Panel#67 (comment) for the same bug.
