I've made a start on this - queue-viewer and (most of) the libraries
log to ~release/var/data/queue-viewer/logs/current, and there's a
secondary log alongside for the bin/queue-viewer wrapper script.

The individual scripts still need a fair amount of work on the log
entries they generate and appropriate severities for them - most of
them will end up in "debug", which doesn't quite feel fine grained
enough.

For now I created the log file as "2018-03" and symlinked "current" to
it. We'll need a monthly cron job to generate the new log files and
update the symlink target (or someone will need to update queue-viewer
to allow patterns in the log filename).
