Comment 8 for bug 1630822

So we have patches up for this, and I've backported https://review.openstack.org/#/c/382698/ to stable/liberty.

I've added OSSA to this since it's probably worth an advisory given you could be providing your cloud credentials in a paste (bug reports) when someone asks you to recreate a bug via openstack CLI with the --debug option and you just blindly send it all over and it's public.
