Store realtime server data

[cs716]

For?

S&Box

What can't you do?

• Access the current lobby LobbyInformation easily
• Set data on the lobby (maybe on the LobbyInformation.Data dictionary) that can be accessed from QueryLobbies
• Add host latency into the LobbyInformation struct or create a way to get the latency from the menu client to the host

How would you like it to work?

Access the LobbyInformation after GameNetworkSystem.CreateLobby(); or through another method available to the host and allow us to set options to the lobby that outside players can access for a matchmaking system or lobby browser such as privacy status, gamemode options that can be changed between lobbies, etc.

What have you tried?

N/A - No way to do this that I can find. For the time being (unless this is an easy implement or there is a way to do this that I'm missing) I'll be using an external API to store and retrieve lobby information by the Id.

I can see the two internal functions that may allow for this:

Additional context

This was brought up by Carson previously in #4482 but was a reply to the issue and doesn't appear to have been implemented

What kind of things do you want to store?

In the network system I'm trying to avoid using lobby specific features, because if you're running a dedicated server etc, it won't have a lobby.

For my game, the state of the game in progress is mainly what I’m trying to store (like preparing, in progress, etc). The idea being players who want to get in and play aren’t joining lobbies where a round is in progress if they don’t want to.
