• new channel
• channel update(new org join into specific channel)
• peer join channel
• peer exit channel
• list channel
• inspect channel config

• chain code lifecycle
• system chain code(as list all chain code)

• gate policy?(common/policydsl/policyparser.go, tool for operator)
• peer discovery(optional, as ping test among peer networks when gateway disabled or fabric version below 2.5)
• base on peer discovery result, generate connection profile for sdk if possible?(optional)
