Review comment:
I think we have to be explicit that the payload is an encoded windowed value
using the beam:coder:windowed_value:v1 coder parameterized by
beam:coder:bytes:v1 elements coder and the window coder that this
param_windowed_value uses.

> The coder of WindowedValue cannot be configured and it’s always
> FullWindowedValueCoder. We don't need to serialize the timestamp, window and
> pane properties in Flink and so it will be better to make the coder
> configurable (i.e. allowing to use ValueOnlyWindowedValueCoder)
