Glare became a separate project during Newton. The code was copied
out of the Glance tree, but remained in the Glance repository. It
is no longer being maintained, and that has begun to cause some
problems, for example, blocking a recent stevedore upper constraints
change; see I141b17f9dd2acebe2b23f8fc93206e23bc70b568
This patch removes the Glare code from the Glance repository. It
includes Alembic database migration scripts, in both the all-in-one
and E-M-C format. It also includes release notes.
Implements: blueprint glare-ectomy
