[FEATURE] Generate API code from OpenSearch API Spec

[VachaShah]

Is your feature request related to a problem?

Related to opensearch-project/opensearch-clients#19

What solution would you like?

Re-use the generator that generates API Code that maintains backwards compatibility with the current client APIs and provides a way to add new APIs.

What alternatives have you considered?

Using OpenAPI generators instead of re-using the existing generator but it makes it difficult to maintain backwards compatibility.

Do you have any additional context?

Hi @tannerjones4075, yes absolutely! The first step would be use to the API specs from https://github.com/opensearch-project/opensearch-api-specification/blob/main/OpenSearch.openapi.json and modify the existing non-functional generator in the go client to create code similar to the existing client. The general idea is to replace all the code (module by module or divided in whatever way works) in this repo for the APIs with code generated from the API specs without breaking the users.
