Auth order spike

[gejohnston]

What It Does

This PR contains a design document proposing how Zowe clients could enable users to specify their own preferred order of authentication.

Certainly, the proposed approach should be the primary focus of reviews. Several secondary items to consider are:

• I purposely chose to place this design document in the Zowe GitHub repository.

  • It is reasonable to allow interested, external people see the design of our open source app before it is implemented.
  • Even after implementation, we can point people to such a document as an easy way to explain how the app is intended to operate.
  • We can consider whether or not we want our future designs to follow this publicly-available approach.

• This is a draft PR.

  • The last section has not been sufficiently investigated to ensure that we have a viable approach. My intention is to do that confirmation.
  • None-the-less, I think it would be good to review the early concepts to confirm whether it is even worth pursuing the details of the last section.

• It will be easier to read the document from the repo than from the file diffs.

• Alternatively, if you download the file and view it in the VSCode "Markdown Preview" window, you get a little splash of color which make some things easier to identify.

Review Checklist
I certify that I have:

• Completed analysis and/or prototype of proposed software
• Created stories for future implementation
• updated the changelog

I know that the tests are failing, but I approve of the design document, hence my approval. Very comprehensive and covered any questions that I had throughout my review. Thanks Gene for writing this proposal.

Given the context of where the changes would need to be made and following up on our previous in-person discussion, we may be able to leverage the Config class for these new functions. ProfileInfo has access to the loaded, merged config instance, so we can leverage this in Zowe Explorer to get access to the authentication order for a given profile. It seems that ImperativeConfig.instance.config might also be valid at the time a CLI command is run, so it could be used to access the authentication order as part of building the session.
