Expose `--network-alias` command line switch
When setting up an embedded mattermost via omnibus-gitlab we need to configure the gitlab container with a sense
that it is both gitlab.example.com
and mattermost.example.com
so
that the rails application can find the co-located mattermost API by
name.
Here we add the code to transform a network_aliases array into multiple --network-alias arguments.
