Handles the /ipfs/ping/1.0.0 protocol. This allows pinging a remote node and waiting for an answer.

Usage

The Ping struct implements the NetworkBehaviour trait. When used, it will automatically send a periodic ping to nodes we are connected to. If a remote doesn't answer in time, it gets automatically disconnected.

The Ping struct is also what handles answering to the pings sent by remotes.

When a ping succeeds, a PingSuccess event is generated, indicating the time the ping took.
