Client side ping’s fail must send warning for a player (instant disconnect and concede problem)

Possible problem: in rare use cases with bad/unstable connection some users can catch instant disconnection and concede.

Possible reason: If game do nothing and no any messages from a server side (e.g. game waiting someone’s action) then only background auto-ping feature help to keep good connection status. But it must be research/confirmed.

Another possible reason: jboss network’s inner timeout and ping fail (example: xmage client has too big ping timeout so jboss network fail first).

Possible fix: inform player in all game chats about ping fail and reconnection require (it must be client side message like messages about connection problem of other players).
