Description

Flight benchmark performs worse when working threads increases. It can be improved by setting gRPC option GRPC_ARG_USE_LOCAL_SUBCHANNEL_POOL to make each client creating its own TCP connection to server, without sharing one connection.
We can add a cmdline parameter to enable/disable TCP connection sharing.
