Allow runner to configure customization WindowedValue coder.
URL: https://github.com/apache/beam/pull/9979#issuecomment-560223094
Hi, @mxm @lukecwik Thanks a lot for your review and suggestions. I think
it's a good idea to use a `WindowedValue` coder to encode the constant values,
and decode the `WindowedValue` at python side. In this way, we don't need to
add protobuf class to define window info. I will try to update the PR according
to your suggestions.
As for the coder name, how about call it `constant_windowed_value`? I
haven't found a better name yet.
Best,
Jincheng

> The coder of WindowedValue cannot be configured and it’s always
