glance-simplestreams-sync doesn't support proxying

[JuanJo Ciarlante]

glance-simplestreams-sync charm installs a symlink as:
/etc/cron.daily/glance-simplestreams-sync.py -> /usr/share/glance-simplestreams-sync/glance-simplestreams-sync.py
, voiding any http_proxy setup done by juju.

FYI this works:
ubuntu@unit$ cat /etc/cron.daily/glance-simplestreams-sync-with-proxy
#!/bin/bash
test -f /home/ubuntu/.juju-proxy && source /home/ubuntu/.juju-proxy
exec /usr/share/glance-simplestreams-sync/glance-simplestreams-sync.py
