[Request] API schema checks on PR

[andrewazores]

Describe the feature

We should dump out the HTTP API definition (openapi) and the GraphQL schema to some files checked in to the repository.

Each time a PR is opened and the container is built, the PR should also dump the new OpenAPI and GraphQL schemas and compare them to the checked-in copies. If there are any diff changes then it should ping maintainers to verify and block the merge until maintainers review and accept the changes, and the schema files are updated to match.

Anything other information?
