Open Stack

I've got a change proposed to disable glance v1 by default in devstack 
for Pike [1].

The glance v1 API has been deprecated for awhile now. Nova started 
supporting glance v2 in Newton and removed the ability to use nova with 
glance v1 in Ocata.

It also turns out that Tempest will do things with glance v1 over v2 
during test setup of glance v1 is available, so we're missing out on 
some v2 coverage.

The time has come to change the default. If you have a project or CI 
jobs that require glance v1, first, you should probably start moving to 
v2, and second, you can re-enable this by setting GLANCE_V1_ENABLED=True 
in the settings/localrc for your devstack plugin.
