Public bug reported:

After this change: https://review.openstack.org/#/c/584504, where we
changed the default value of queued_for_delete column from False to NULL
in the sqla code for the instance_mappings object (to do the data
migration for queued_for_delete), we forgot to set the default value as
False upon creation of the new instance_mappings in the create() method.
Hence new instance_mappings always ended up with NULL values in the db
meaning the data migration "populate_queued_for_delete" would never
finish.

So in the InstanceMapping.create() function queued_for_delete should
always be set to False() explicitly so that new mappings get False as
the default value.
