Updated to version 8.1.0

Fix for intermittently failing rate limiting test
Added ConnectionId to RequestDefinition to correctly handle connection and path rate limiting configuration
Added ValidateMessage method to websocket Query object to filter messages even though it is matched to the query based on the  ListenIdentifier
Added KlineTracker and TradeTracker implementation
