Subject: [PATCH] handle PacketPlayInKeepAlive async and revert keepalive limit
In 1.12.2, Mojang moved the processing of PacketPlayInKeepAlive off the main
thread, while entirely correct for the server, this causes issues with
plugins which are expecting the PlayerQuitEvent on the main thread.
In order to counteract some bad behavior, we will post handling of the
disconnection to the main thread, but leave the actual processing of the packet
off the main thread.
We also revert the bump on the servers built in keepalive back to 15 seconds,
this solves a read timeout in scenarios where the client isn't sending data to
the server, e.g. spectating an entity.
