Prevent players with bad connections from joining the matchmaker

[Askaholic]

The biggest question is how the heck to figure out that a player has high latency. We could measure latency to the lobby server but that won't necessarily be an accurate prediction of in game connectivity since the in game traffic won't necessarily be routed through the same server.

Another suggestion was to apply similar timeout rules if you abandon a game on purpose on the first few minutes. Detecting that gets tricky though

Timeouts for abandoned games should probably discussed in the issue about the matchmaking bans #870

We should monitor the situation once we have the bans for queue dodging if this really is a problem that needs to be adressed

There should be no reason anyone now cannot connect and play. There is plenty of bandwidth for this game. The code needs to be improved so there is no connection issues.
Even on 1gps up and down connection I am using, I see many games not working or launching with matchmaking.
