> the log of notification about LE is very important to help us to see the
> process of LE:e.g.
> {code:java}
> 2019-01-01 16:29:27,494 [myid:2] - INFO
> [WorkerReceiver[myid=2]:FastLeaderElection@595] - Notification: 1 (message
> format version), 3 (n.leader), 0x60b3dc215 (n.zxid), 0x3 (n.round), FOLLOWING
> (n.state), 1 (n.sid), 0x7 (n.peerEpoch) LOOKING (my state){code}
> the current log have some problems:
> 1:don't use the placeholder(other:+),don't in the style of k:v（antiman）
> 2.the properties in the logs are very messed(no group by,no order), not easy
> to read.
> 3.the value about version is HEX which don't have the 0x prefix.
