PIP-53: Keyed window function

Hi all,

Recently, we are facing with the demand to mimic Apache Flink's keyed
window operator in Pulsar Functions.

This is because, with simple keyed window functions, we could remove the
need to deploy and run a separate computing cluster with little
computations to do.

Therefore, I've drafted PIP-53: Keyed window function to enable this
feature in Pulsar.

This design doc is available at

Please help to review, any ideas are welcome.

Best,
Yijie
