things to consider - whether everything is migrated to 0.6.0

notes for API/CLI:

• asset metadata will need to migrated for existing dandiset (without asset id modification)
• dandiset metadata will need to migrated for existing dandiset drafts
• for any published version including some where we need to adjust licenses.
• CLI should move up to this version and declare prior versions to be upgraded and add more validation logic
