Call kind delete cluster until success delete

Docker sometimes fails deleting workers:
  - Container failed to exit within 10s of kill - trying direct SIGKILL
  - cannot remove container "kind-worker": could not kill container: tried to kill container, but did not receive an exit event

kind delete cluster is an idempotent operation, meaning it may be called multiple
times without failing (like "rm -f"). If the cluster resources exist they will be deleted,
and if the cluster is already gone it will just return success.
