KAFKA-3818: Change Mirror Maker default assignment strategy to round robin
Update Mirror Maker to use round robin assignment by default since it gives
a better balance between the instances, in particular when the number of Mirror
Maker instances exceeds the typical number of partitions per topic. There
doesn't seem to be any need to keep range assignment since co-partitioning is
not an issue.

KAFKA-3818: Change Mirror Maker default assignment strategy to round robin
It might make more sense to use round robin assignment by default for
Mirror Maker since it gives a better balance between the instances,
in particular when the number of Mirror Maker instances exceeds the typical
number of partitions per topic.
There doesn't seem to be any need to keep range assignment since
copartitioning is not an issue.
