   ### Issue description
   
   1. downstream connection management
   client -->apisix -->service
   in sometime, client application heartbeat message lost, or need discard connection, or other reason,
   can apisix actively force close TCP connection?
   
   2.  Bidirectional streaming gRPC support
   my service have Bidirectional streaming gRPC, which to push some message to client.
   
   client only one http2 connection to apisix,and apisix deliver different request to backend service,
   some service is unary call, 
   but push service is bidi stream grpc,
   I need the apisix hold the upstream connection， so that push message to the client

   > 1. can apisix actively force close TCP connection?
   
   Closing the connection should be something done by the client or upstream, and the gateway actively closing the connection is usually in a timeout situation.
