Could this be solved instead by having a global config for Certbot that
sets default values for certain flags? For instance, right now
--renew-hook defaults to the empty string. But what if an OS packager
could default it to "run-parts /etc/ssl/renew-hooks.d/" ? The global
defaults approach would also be a nice solution to the question about
log rotation defaults, since OS packagers that know there is a logrotate
config could set the --max-log-backups flag appropriately.

I think this only works if the package is part of an OS, and so the
package maintainer knows exactly where to put the hooks. So I think the
idea above would also work for this case.
