Renewal portion of the cron jobs are no longer needed

[dale-c-anderson]

Cron is sending out notifications that the certbot process is already running.

It turns out that the snap version of certbot comes with a built in systemd timer (view them all with systemctl list-timers) which performs renewals automatically. However certbot's renewal does not automatically reload http dameons to pick up the new cert version.

So the cron jobs need to be modified to only test + reload the web config, instead of renew + test + reload.
