Code review comment for lp:~lathiat/charms/trusty/glance-simplestreams-sync/trunk

Ok, I was wrong above (too many things going on at once). This branch does work, but might hit a bit of a race with swift setup and thus hit the ClientException as above.

I've worked around that using https://pastebin.canonical.com/154167/ (mostly whitespace fixes, but also adding exception handling to keep the per-minute cronjob if swiftclient.ClientException is caught). In my last run, I haven't hit it, but as I said, it will sometimes happen with automated installs and sometimes not.
