glance/bin/glance-manage
Eoghan Glynn 71c98ae887 Support DB auto-create suppression.
Adds a new boolean config option, db_auto_create, to allow the
DB auto-creation be suppressed on demand. This defaults to True
for now to maintain the pre-existing behaviour, but should be
changed to False before the Folsom release.

The 'glance-manage db_sync' command will now create the image*
tables if the DB did not previously exist. The db_auto_create
flag is irrelevant in that case.

The @glance.tests.function.runs_sql annotation is now obsolete
as the glance-api/registry services launched by functional tests
must now all run against an on-disk sqlite instance (as opposed
to in-memory, as this makes no sense when the DB tables are
created in advance).
