server: commit Metadata OpenAPI spec with CI check, add Typescript client scaffolding

## Description Adds `metadata.openapi.json` to version control. Adds a Buildkite job that verifies the spec is up-to-date on server changes, and fails the CI pipeline if not. Adds scaffolding for a new Typescript project that consumes that OpenAPI spec, and produces Typescript types. This is adapted from the similar existing data connectors project in `dc-agents/dc-api-types/`. Generated code is *not* committed to version control. Instead there is a script to generate code on-demand at publishing time. There are plans to incorporate publishing the generated project to NPM using a forthcoming pipeline that the Console team is working on. For the moment the Typescript project is under `metadata-api-types/typescript/`. The plan is to move the project in a future PR to the frontend sub-monorepo.

+# Hasura GraphQL Engine Metadata API Types
+
+This package contains TypeScript types for working with the Hasura GraphQL
+Engine Metadata API. That is the API that is used to configure the GraphQL
+Engine.
+
+Currently this library exports types used for exporting and importing GraphQL
+Engine metadata in its entirety. To get the root type for exported metadata,
+import the `MetadataV3` type.
+
+```ts
+import type { MetadataV3 } from '@hasura/metadata-api'
+```
+
+The other types provided by the library are aliases for types of properties that
+appear within the metadata export.
