OpenWebTorrent disconnects clients after two minutes of inactivity. In a scenario where an
announce occurs and no other activity occurs for the (default) 120-second idle timer, the
websocket will be torn down by OpenWebTorrent. This in turn causes the tracker client to wait one
minute, reconnect, and reannounce its peers.
This patch sends a websocket.PingMessage every 60 seconds to maintain the connection.
On socket reconnect, reannounce any webrtc offers that might have been half-open before the
socket reconnected. This implementation closes any existing half-open offers and republishes them,
but does nothing to existing webrtc connections which are still running (these are cleaned up
elsewhere and are not owned by this code)
