Overview of changes

• Now any API calls in Querybook will have strongly typed input/output values.
• This should also make updating API easier as there is now only 1 entrypoint to the API itself.
• API endpoints are now grouped by resource names, making them easier to find
• useDataFetch is now useResource, the hook became simpler as it only needs to memo the function.

Minor logic changes:

• swap query engine now return null
• removed unused task_type variable from /schedule/int:id/record/
• fixed a bug where form does not close when creating warnings
• Removed default return type = any for API calls, now it would return unknown if not specified
• fixed an issue where download csv would not work for localhost:port

Tests:
Manually verified APIs to work locally, typing and linting should also have no exception cases as well
