OK, we'll work on a utility which can be run on a Juju controller server to
extract all the logs from the database, even when the Juju server isn't
running.

Note that there is also already a last resort logsink.log file generated on
each Juju controller server which records the last 1GB of logs received by
that server. If you grab this file from each server and merge them you end
up with the all the recent logs.
