feat(extensions): add support for different json body types (array or object)

[reubenmiller]

Support a new contentType in the extension definition to specify whether the json body should be an array or an object. This influences how the paths are interpreted in the parameter sections.

Two new types are supported under .commands[].bodyContent.type

• jsonobject
• jsonarray

These values have also been added to the json schema (to make it easier to consume.

Example command (snippet)

  - name: example
    path: inventory/managedObjects
    description: Create object
    method: POST
    bodyContent:
      type: jsonarray
    body:

        property: 0.name
        description: property of an array
