* prep for processing the structured run output

* undo unwanted change to a json key

* Add skeleton functions and API for refactored renderer

* goimports

* Fix documentation of the RenderOpts struct

* Add rendering functionality for primitives to the structured renderer

* add test case for override

* Add support for parsing and rendering sensitive values in the renderer

* Add support for unknown/computed values in the structured renderer

* delete missing unit tests

* Add support for object attributes in the structured renderer

* goimports
