legacy2openapi-spec - Legacy to OpenAPI spec conversions of APIs for easy SDK code generations

OpenAPI spec-compliant APIs have the below advantages:

1. Can generate SDK codes automatically using the OpenAPI Generator
2. Can generate API playground & documentation using openapi-ui and Swagger UI
3. Can generate nice-looking documentation using Redoc

But, few SaaS companies don't offer OpenAPI spec for their own reasons. This project is an attempt to identify those legacy API documentation and convert them into OpenAPI spec.
