[FLINK-758] Add initial value to GenericReduce and adjust AllReduceDriver
This is an initial version of introducing an initial value to the reduce
functions. Thanks to @fhueske for suggesting to add the initial value to
`GenericReduce`.
It is only implemented for `AllReduce` (ungrouped reduce). Please give
feedback. If everything is OK, I would continue (~ 1 hr) with the remaining
reduce variants (grouped reduce, ungrouped groupreduce, and grouped
groupreduce).
