LinkLocalIPs missing from ServiceNetworkConfig struct

[Jeremiah Millay]

The compose spec supports link_local_ips for a service network config. In looking at why this field is not honored in compose v2 I discovered that compose-go is missing support for this in ServiceNetworkConfig. Related issue for compose is here: docker/compose#9659

I believe that adding support for this field is a prerequisite to being able to fix this in compose as it has a dependency on compose-go.
