Antoine Leblanc 3a400fab3d Rewrite OpenAPI ... ### Description This PR rewrites OpenAPI to be more idiomatic. Some noteworthy changes: - we accumulate all required information during the Analyze phase, to avoid having to do a single lookup in the schema cache during the OpenAPI generation phase (we now only need the schema cache as input to run the analysis) - we no longer build intermediary endpoint information and aggregate it, we directly build the the `PathItem` for each endpoint; additionally, that means we no longer have to assume that different methods have the same metadata - we no longer have to first declare types, then craft references: we do everything in one step - we now properly deal with nullability by treating "typeName" and "typeName!" as different - we add a bunch of additional fields in the generated "schema", such as title - we do now support enum values in both input and output positions - checking whether the request body is required is now performed on the fly rather than by introspecting the generated schema - the methods in the file are sorted by topic ### Controversial point However, this PR creates some additional complexity, that we might not want to keep. The main complexity is _knot-tying_: to avoid lookups when generating the OpenAPI, it builds an actual graph of input types, which means that we need something similar to (but simpler than) `MonadSchema`, to avoid infinite recursions when analyzing the input types of a query. To do this, this PR introduces `CircularT`, a lesser `SchemaT` that aims at avoiding ever having to reinvent this particular wheel ever again. ### Remaining work - [x] fix existing tests (they are all failing due to some of the schema changes) - [ ] add tests to cover the new features: - [x] tests for `CircularT` - [ ] tests for enums in output schemas - [x] extract / document `CircularT` if we wish to keep it - [x] add more comments to `OpenAPI` - [x] have a second look at `buildVariableSchema` - [x] fix all missing diagnostics in `Analyze` - [x] add a Changelog entry?
