[ionutbalutoiu, r=thedac] Adds additional variables to the image-service relation. These are available only when a relation with Swift object storage is present.
In case any charm needs to generate temporary URLs from Glance with Swift backend, it needs a temp-url-key which must be posted to Swift with the glance account. (Details: http://docs.openstack.org/liberty/config-reference/content/object-storage-tempurl.html)
This is needed for OpenStack Ironic charm (http://bazaar.launchpad.net/~cloudbaseit/charms/trusty/ironic/trunk/view/head:/hooks/ironic_context.py#L76), but might also be generally useful.
