Tasks for Kubernetes 1.26

[sbueringer]

This issue is tracking the list of tasks that should be implemented when Kubernetes v1.26 is released.
Currently, we are waiting for the Kubernetes release and we will for a few months, mostly opening this already for tracking purposes

For prior art please see #6661

• CI:

  • CAPD:
    • docker.yaml: KUBERNETES_ env vars in variables
    • kind_provider.go, docker/*, ... (just grep for the previously used version in CAPD)
  • Jobs:
    • Add new periodic upgrade jobs, for all release where we want to support the new Kubernetes version
    • Adjust presubmit jobs so that we have the latest upgrade jobs available on PRs (for all releases)
    • Update INIT_WITH_KUBERNETES_VERSION

• Book:

  • Update and test quickstart
    • 1.24 PR 🐛 Use Kubernetes 1.24 in quickstart and CAPD, bump to kind v0.14 #6513
  • Update supported versions in versions.md
  • Update job documentation in CAPI (jobs.md)

• Release specific issues:

• After a Kubernetes release is cut a controller-runtime version is created. When the CR version is available we have to:

  • Bump controller-runtime to use new Kubernetes Go libraries (controller-runtime, controller-tools, client-go, ...)
    • This can include upgrading the Go version (we're using the same as k/k)
  • Update KUBEBUILDER_ENVTEST_KUBERNETES_VERSION in Makefile
  • Bump conversion-gen in Makefile via CONVERSION_GEN_VER
  • If the new Kubernetes version uses a new Go version
    • Jobs: Update kubekins-e2e images used for jobs running against main
      • Potentially it makes sense to switch to the latest ("master") version of kubekins-e2e if there is no -{KUBERNETES-VERSION} tag of the image already.
    • Update go version:
      • .github/workflows
      • .golangci.yml (+ corresponding workflow file)
      • cloudbuild YAMLs (to use an image with the current go version)
      • hack/ensure-go.sh
      • netlify.toml
      • Makefiles
      • Tiltfile
      • [opt] go.mod files (only if we want to increase the minimum supported version of consumers) [DOES NOT APPLY]
