Ian Wienand a44f2e6767 Run expand-groups.sh occasionally under cron
We only run expand-groups.sh during launch-node -- which makes sense
for additions as we don't have hosts appearing that don't come via
that path.  However nothing really runs it on removal of hosts,
meaning /etc/ansible/hosts/generated-groups can contain old entries
until the next time a new host is launched.  Simply run it once a day
to keep it fresh.
