Julie Pichon 4609c7a9c2 Provide a default for OPENSTACK_IMAGE_BACKEND
The list of image formats has become customisable, but didn't have a
default which can cause issues since it's a required field when
creating a new image. Also document the setting.

Additionally, mark OpenStack settings documentation as "(Partial)"
until #1221115 is closed.
