------------------------------------
I have the initial changes (without the Unit tests yet) here
[https://github.com/izzyacademy/kafka/commit/c7094fae666f407e413c2b9d40e980a68aebf81f]
Please let me know what you think. I will be working on the Unit tests in about
a day and will submit a PR with once the Unit tests are completed.

> Currently, the grace period is set to retention time if the grace period is
> not specified explicitly. The reason for setting the default grace period to
> retention time was backward compatibility. Topologies that were implemented
> before the introduction of the grace period, added late arriving records to a
> window as long as the window existed, i.e., as long as its retention time was
> not elapsed.
> This unintuitive default grace period has already caused confusion among
> users.
> For the next major release, we should set the default grace period to
> {{Duration.ZERO}}.
