This pr has the same problem as cita's pr.

Doesn't notice the definition of name/support_version. Used the default definition, which is /p2p/{protocol_id}.

In fact, the protocol id is just an internal index, so there is no need to expose it externally. The same protocol for each service can be implemented internally as a different id

This PR breaks integration test, could you help to debug?

it looks like node cannot connect to peers.
