Automate/review consistency between HTTP API endpoints and the OpenAPI specification

[mrekucci]

In our codebase, it is difficult to maintain consistency between HTTP API endpoints and the OpenAPI specification. Try to think of ways to make it simpler and more automated. Consider generating the OpenAPI specification from the Golang source code, etc... If there is no simple or elegant way to achieve this, manually review that our OpenAPI specification matches one-to-one with our HTTP endpoints.
