Add support for OData V3 specifications #235
Description
User story
It should be possible to use the APIM-CLI to import OData V3 Metadata-Specifications into the API-Manager without the need of an additional converter.
For that, the APIM-CLI should internally convert the OData-Metadata-Specification into an OpenAPI 3 spec and import it as any other API.
Please vote only once on the issue (OData V3 (this issue) or OData V4) that has a higher priority for you. Since OData V3 and V4 are massively different, support for both versions cannot be added at the same time. Maybe V3 will not be supported at all, because it is not widely used.
Please vote on this issue 👍 if you have need for this feature. It would also help, if you can share a OData Metadata-Description which can be used for Unit-Testing the converter.
