Document Step parameters in Step/Pipeline output products

[stscijgbot]

Issue JP-1083 was created by Jonathan Eisenhamer:

Currently, information about what steps and pipelines ran on a given data file is recorded, including reference files used, steps executed and skipped, etc.

However, a glaring omission is the documenting of what the {{Step}}/{{Pipeline}} parameters were during execution. Now, with the ability to retrieve parameters from CRDS, this documentation is now critical information.

As such, a minimum set of information to be placed into output product headers should be:

• {{Step}} parameters and their values
• CRDS parameter reference file used, if one was found
