[Action Required] Removing Bazel Build from Kubernetes

[Benjamin Elder]

Hello Kubernetes Contributors!

We are nearing alpha-completion of KEP #2040 "Reducing Kubernetes Build Maintenance".
SIG Testing and SIG Release have decided to reduce our maintenance load in the core Kubernetes repo to a single build system. You can read more on why in the KEP.

As a result: kubernetes/kubernetes#99561 removed the bazel build, in favor of focusing on the singular make build we have always shipped releases with.

NOTE: This only affects the core Kubernetes repo. Sub-projects can continue to make their own decisions about build tools. It also does not affect existing release branches.

What do you need to do?

If any of your in-flight PRs have any generated BUILD changes (e.g. from adding or removing go source files) you should:
- fetch and rebase against upstream
- run hack/update-bazel.sh during your rebase which will now auto-remove any lingering changes in your PR once the updated script merges in #99561. This script should only take about one second to run.
- carry on as usual

How can I get help if I run into issues, or have questions?

Please feel free to reach out to me with any problems and I will respond ASAP.

I ask that you please do so in #kubernetes-contributors, ping @bentheelder in this channel so other contributors can benefit from the answers and / or beat me to responding :-)

Thank you for your time reading this and in advance for your patience with rebasing.

- Ben

The second Kubernetes Contributor summit, which was the first one I
attended, adding bazel to our build infra was the main topic of discussion.

Now you see it, now you don't. Great work, Infra team.
