Improve event "node error" to know which node (host+port) of cluster fired it

[nolimitdev]

When "node error" event happens on cluster node there is no info in its argument about which node error issued.

redis.on('node error', (error) => {
    log('Redis cluster node error:', error.message);
});
// Redis cluster node error: Connection is closed.
// Redis cluster node error: timeout

I tried to log entire "error" object but there is no info about node. It is important to quickly know host and port of node which has some problems.
