KAFKA-3561: Auto create through topic for KStream aggregation and join [WIP]
@guozhangwang can you please take a look at this? It is not close to being
done but i'd like some feedback to ensure i'm heading down the right path and
understand what this JIRA is asking. The main things to look at are the
`KStreamImpl.map(...)` method I added and the change made to
`TopologyBuilder.copartitionGroups`
There is also a test, `KStreamRepartitionMappedKeyTest`, that passes with
these changes.
