Remove duplicated glance paste config.
Remove duplicated glance paste config.

When glance paste config was split out from the core config,
devstack duplicated the former in both files in order to work
around the chicken-and-egg problem with the glance change being
gated on devstack passing.

This transitionary arrangement is no longer required so may now
be removed.
