KAFKA-3111: Fix ConsumerPerformance output for zero interval lengths
Interval lengths for ConsumerPerformance could sometime be calculated as
zero. In such cases, when the bytes read or messages read are also zero a NaN
output is returned for mbRead per second or for nMsg per second, whereas zero
would be a more appropriate output.
In cases where interval length is zero but there have been data and
messages to read, an output of Infinity is returned, as expected.
