* Reorganize the db migration .sql scripts into individual schema version directories and generate the sql httpfs fakeFile accordingly. * Created a /dev schema version directory to hold db schema updates that have not been finalized. * Add an 'allow-development-migrations' flag to allow `boundary database init` to be executed even when there are schema updates in /dev.
