@aleskandro ci/prow/shellcheck failed and complaining about X prefix
i did not complain about before:

Avoid x-prefix in comparisons as it no longer serves a purpose.
Did you mean:
echo "Require $N_MASTERS masters and $N_WORKERS workers $([ "$REQUEST_BOOTSTRAP_HOST" == "true" ] && echo -n '(+ 1 bootstrap node)') = $NUM_HOSTS hosts"

should I follow their advice?

Hi @jadhaj , can you rebase to doublecheck shellcheck? You shouldn't care about a script you didn't modify.
