I haven't tried out this solution, so I am not exactly sure what gets
printed (I can do it over the weekend sometime). At a high-level my comment is
that every attempt that checks if the cluster is `ssh-ready` should print some
feedback on the screen so the user knows the script is not hun. If that is the
case I'm fine with this solution.
