Open Stack

Thanks for your digging and help with this Ian and Andreas.

I've added an apache rule to redirect -'s to .'s as a quick workaround to
un-wedge the gate https://review.openstack.org/#/c/314898/ (and a few edge
cases https://review.openstack.org/#/c/314956)

If you have a build that has failed due to "No matching distribution found
for <package with "." in name>" it should be safe to issue a 'recheck' now.

There may be some more edge cases so let us know if you run into any.

We should, as suggested, fix bandersnatch or perhaps pin pi as soon as
possible. Once fixed properly we should undo the workaround so that our
mirror matches pypi.

Cheers,
Josh
