This flag is a temporary conf value to segregate paths between glance v1
and glance v2 API usage inside the nova image proxy. This is set to True
by default to use Glance V1 APIs as default. However, it would be flipped
to False, once the nova image proxy is ready to adopt V2 APIs. Eventually
this flag would be deprecated once the proxy gets rid of all the glance
V1 API code.
This flag allows reverting to glance v1 if for some reason glance v2 doesn't
work in your environment. This will only exist in Newton, and a fully working
Glance v2 will be a hard requirement in Ocata.

features:
- Nova now defaults to using the glance version 2 protocol for all
backend operations for all virt drivers. A ``use_glance_v1``
config option exists to revert to glance version 1 protocol if
issues are seen, however that will be removed early in Ocata, and
only glance version 2 protocol will be used going forward.
upgrade:
- It is now required that the glance environment used by Nova
exposes the version 2 REST API. This API has been available for
many years, but previously Nova only used the version 1 API.
