Reduce the number of retries on cert creation (#664)

Retrying multiple times on cert creation doesn't usually help but
makes the user wait for a longer time for nothing. Usually there
is either a configuration error that must be solved or the DNS
change hasn't propagated yet, which will usually take longer than
the retry window.
