Plus refactoring of the KillAllXXXActions and tests to share common code. This essentially completes the KillAll []s. We can now reliably clean out everything except for: * Lock - harmless to leave alone or delete from the gae console * GaeUserIdConverter - same * RdeRevision - filed [] to track, but harmless if not cleaned up * ForeignKeyHostIndex of renamed hosts - tracked in [] ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=120781975
