caddy-frontend: Log to supervisor

Caddy's -log can log to file, but there is no control over logrotation, so
it resuls with leftover logrotated files in the instance. As we have
already system to catch process logs (supervisor) move the logging there.

error-log stays for errors of catch-all and various non-slave instances.
