Thanks for doing this - the minor change for the --request-timeout is something I had forgotten to include originally. It can help address kubectl hanging when something goes wrong (like another master rebooting and it happens to be the one that the kubectl is trying to talk to)

Minor addition - all of the kubectl command should also have --request-timeout 30s (or pick your number) since the reboots of another node may hang the kubectl command otherwise.
For example:
kubectl --request-timeout 30s annotate namespace ${LOCK_NS} ${LOCK_NAME}=${NODE_ID}
