MINOR: Correct the ConsumerPerformance print format
Currently, the output of `ConsumerPerformance` looks strange. Before the
`header` format as follow:
```
"time, threadId, data.consumed.in.MB, MB.sec, data.consumed.in.nMsg,
nMsg.sec"
```
while the `body` as follow:
```
println("%s, %d, %.4f, %.4f, %d, %.4f".format(dateFormat.format(endMs), id,
totalMBRead,
1000.0 * (mbRead / elapsedMs), messagesRead, ((messagesRead -
lastMessagesRead) / elapsedMs) * 1000.0))
```
So we get the follow result:
```
time, data.consumeed.in.MB, MB.sec, data.consumeed.in.nMsg, nMsg.Sec
09:52:00, 0, 1100.3086, 220.0177, 563358, 112649.0702
```
So the `header` and `body` mismatching.
And also, this pr makes the functions more readable.
