certbot logs are not persistent

[frafra]

/var/log/letsencrypt is used to store logs by default, as certbot does not seem to output to stderr when something files (which would be a more appropriate behaviour in a containerized environment).

A solution would be to add a persistent volume for the logs here: https://github.com/GeoNode/geonode-project/blob/e21cc1b398fe1b46042c766bfc276b798f11d4de/docker-compose.yml#L82-L84

An alternative could be just to display the whole log file after the program is executed, then drop the file, etc.
