Code review comment for lp:~jaypipes/glance/checksum

I noticed that there is no migration script to add the checksum column. Trunk is already missing a migration for disk_format/container_format, but we probably shouldn't get in the habit of merging to trunk without migrations, since that effectively leaves trunk broken. However, the tests seem to run fine without the migration.

I tried merging trunk into this branch to test these changes with the glance cli tool, but there were conflicts so you may want to merge trunk once more.

Otherwise, this looks good to me. I'm going to mark it as Needs Fixing because of the missing migration. If you think it's ok to merge this to trunk without the migration then let me know and I'll mark this approved.
