Create Schema Manager and propagate contexts into the DB calls downstream.
Add checks at controller startup and database init for correct schema version and schema migration dirty bit being set.
* 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.
This also then removes support for docker-based containing starting (for
now) from platforms other than windows/darwin/linux as there are build
issues on several.
