# This file is a barebones file needed to file a gap until Ansible 2.0. No error
# checking, no deletions, no updates. Idempotent creation only.

# If you look closely, you will see we arent _really_ using the shade module
# we just use it to slightly abstract the authentication model. As patches land
# in upstream shade we will be able to use more of the shade module. Until then
# if we want to be 'stable' we really need to be using it as a passthrough
