MINOR: stats: report the number of currently connected peers
The active peers output indicates both the number of established peers
connections and the number of peers connection attempts. The new counter
"ConnectedPeers" also indicates the number of currently connected peers.
This helps detect that some peers cannot be reached for example. It's
worth mentioning that this value changes over time because unused peers
are often disconnected and reconnected. Most of the time it should be
equal to ActivePeers.
