RFC: The Feast Kubernetes Operator (The Open Source Feature Store)

I'm a maintainer for Feast (https://github.com/feast-dev/feast) (the Open Source Feature Store) and the Feast community is working on creating a Kubernetes Operator for deploying Feast on Kubernetes and would love any feedback you have before we get started!

Here is the GitHub issue: https://github.com/feast-dev/feast/issues/4561, a design doc: https://docs.google.com/document/d/1vGKMizf3_14IyiF_W_Ik7CR0..., and a Slack channel: https://communityinviter.com/apps/feastopensource/feast-the-...!

Thanks a ton in advance for your interest/comments!
