"""Utility for scanning the database to look for NULL instance uuid rows.
Scans the backing nova database to look for table entries where
instances.uuid or instance_uuid columns are NULL (except for the
fixed_ips table since that can contain NULL instance_uuid entries by
design). Dumps the tables that have NULL instance_uuid entries or
optionally deletes them based on usage.
This tool is meant to be used in conjunction with the 267 database
migration script to detect and optionally cleanup NULL instance_uuid
records.
:param delete: If true, delete NULL instance_uuid records found, else
just query to see if they exist for reporting.
:returns: dict of table name to number of hits for NULL instance_uuid rows.
