### background When I use the stream module to test stream proxy_protocol, It can not add not a listen option like [reuse] or [proxy_protocol]; so that I can add to configure easily, we can only use `add_block_preprocessor` to do this; ### Solution Enhancement: ADD stream listen option so that we can use short case easy ### Design Naming: steam_listen_option ### Use Case --- steam_listen_option proxy_protocol --- steam_listen_option2 proxy_protocol
