    ./client -n -d 127.0.0.1 -p 9001 -m notify_message

Test NotifyMsg

1. task build
2. ./bootstrapper : to start bootstrapping server
3. ./server run first server
4. ./server run second test server 

// imitate another module send notify message to gossip API
5. ./client -n -d  127.0.0.1 -p 9001 -t 1  

// trigger one gossip node spread notify message to its neighbour
6. ./client -a -d 127.0.0.1 -p [API_PORT_OF_A_NODE] -m randomm -ttl 3

all receiving gossip node will handle the notify message if there is matching in notify Channel
