### Description As part of the cache building process, we create / update / migrate the catalog that each DB uses as a place to store event trigger information. The function that decides how this should be done was doing an explicit `case ... of` on the backend tag, instead of delegating to one of the backend classes. The downsides of this is that: - it adds a "friction point" where the backend matters in the core of the engine, which is otherwise written to be almost entirely backend-agnostic - it creates imports from deep in the engine to the `Backends`, which we try to restrict to a very small set of clearly identified files (the `Instances` files) - it is currently implemented using a "catch all" default case, which might not always be correct for new backends This PR makes the catalog updating process a part of `BackendMetadata`, and cleans the corresponding schema cache code.
