Extremely Fast Iteration

## Feature Description
Ability to iterate in development or production at the speed of thought. Metadata changes are reflected instantly in the GraphQL API. Any breaking changes are automatically warned or flagged.

## User value / outcome
Users should be able to evolve their metadata and easily deploy changes extremely rapidly. Similar to the developer experience in Linux, there will be a new CLI watch command, allowing you to iterate rapidly and see live changes to your API. This is an improvement to the current experience with V2, where one needs to export/import metadata for every change and/or manipulate metadata API objects one by one. With V3, we will simplify the metadata API to just a 'reload' endpoint.

## Current status (design, alpha, beta etc.)
Currently under development and will be available as early as the Beta release of V3 in June 2023
