[Merge] ~gboutry/ubuntu/+source/python-keystonemiddleware:master into ~ubuntu-openstack-dev/ubuntu/+source/python-keystonemiddleware:master

[Nick Rosbrook]

Review: Approve

LGTM.

For the future, condier adding debian/upstream/signing-key.asc since upstream has detached signatures in place. I manually verified against the Flamingo key in this case.
