Fix Reach limit of connections error
in fe.conf , arrow_flight_token_cache_size is mandatory less than qe_max_connection/2. arrow flight sql is a stateless protocol, connection is usually not actively disconnected, bearer token is evict from the cache will unregister ConnectContext.

Fix ConnectContext.command not be reset to COM_SLEEP in time, this will result in frequent kill connection after query timeout.
