Discovering servers

Before we can connect to any steam servers, we first need to know what servers are available.

Servers are provided trough a ServerList, while you can manually specify a list of servers, the usual method is to use the steam web-api to discover a list of servers with ServerList::discover.

Once you have a server list you can save a copy of the server list for future use. But be aware that if you're re-using an old server list, some server in the list might no longer be functional, so be prepared with dealing with connection issues when trying to connect using a re-used ServerList.
