MinIO/S3 clients generate a _lot_ of requests. It's also not
particularly useful to have these stored in Loki anyway. As such, we'll
stop routing them to syslog/journal.
Having access logs is somewhat useful for troubleshooting, but really
for only live requests (i.e. what's happening right now). We therefore
keep the access logs around in a file, but only for one day, so as not
to fill up the filesystem with logs we'll never see.
