Small change to make the config easier to understand.

Thanks for the PR, but the change seems to be incorrect -

when RTTMillisecond is 100 milliseconds and the election interval is expected to be 1 second, ElectionRTT should be 10.

[siennathesane]

Is ElectionRTT a multiplier or a length of time? I can make the change, I just want to make sure I understand it.

@lni would you be able to provide clarification on my previous question?

[coufalja]

Even though I am not @lni I think I can answer your question: ElectionRTT and HeartbeatRTT are both multipliers of RTTMillisecond.

[lni]

@coufalja is correct.

@mxplusb I had a quick look at the godoc in config/config.go, there are concrete examples on the definitions of both ElectionRTT and HeartbeatRTT. Would you like to have a look and provide feedback on whether it is still a little bit difficult to understand. Thanks.
