fix(domains): renew --no-random-sleep-on-renew

letsencrypt is consistently the longest state in my configuration, and
apparently because of the random delay introduced when renewing
non-interactively. Conceivably this could be made optional using a
pillar variable; but, for now, I'll just disable the random sleep, at
least during dry-run.
