Thanks for the feedback @tillrohrmann, @twalthr!
I've moved the classes to `org.apache.flink.api.table.runtime` and tried to
shorten the aggregates code using Numerics. I only left `AvgAggregate` as is,
because integer average and float/double average are computed differently. We
can always replace it with code generation later as @twalthr suggested.
