Allow certbot to create /var/lib/letsencrypt and /var/og/letsencrypt with
the correct contexts.
Allow it to read /dev/urandom, dontaudit attempts to write python cache files
(would be good to fix python for this), and reload web server to get new
keys.
I think this is good to merge.

There is no relabelto. What is happening here?
