…Conn when we are done with it. In the cluster commithook, we had a failure mode where we would leak a *grpc.ClientConn without closing it. It turns out, if an outbound request has made on a ClientConn, it will continue retrying the connection. And we would leak one on a fixed interval, resulting in ever-increasing CPU utilization.
…ally added conn member.
