No longer uses Hugo /data.
Removes dependency on the Hugo-data-to-pages script.
For each product endpoint, generate a page with the endpoint spec inside the frontmatter.
Writes endpoint specs into each page's frontmatter.
Assign a `type` property for API reference (OpenAPI) paths. For example, if the page structure is `content/influxdb/v2/api/v2/[OpenAPI path]`, then add `type: api_path` to the frontmatter and, if necessary, specify a layout: `layout: api_path`.
Renders the spec param JSON using Rapidoc.
TODO:
- Cleanup
- Create additional templates that process page data for nav, filtering, links, code samples, etc.
- Fix circular reference issues in specs that prevent generating a dereferenced JSON bundle (which could also help us our own custom UI...should we choose).
