network: preserve backwards compatibility

The new network parser will support specifying multiple networks in the old format where each new non-indexed "lxc.network.type" line starts a new network configuration. This way we don't break users. For now, we just print a deprecation warning. We will KILL this in LXC 3.0. Signed-off-by: 's avatarChristian Brauner <christian.brauner@ubuntu.com>
