Fix Glance smoketest to not be written for Diablo. [1/2]

The Glance was initially wrotten for Diablo, which did not have
Keystone to act as a central repository, and so was much more
complicated than it had to be.  This pull request simplifies it.

It also makes the Keystone smoketest actually say where Keystone is.
