Support for 'stack output' command (reopened)

[mikocot]

This PR introduced support for pulumi stack output command in addition to the existing ones.

The reasons for this change are explained in the following issue:
#868

I've chosen output as a name for the command as it reflects the method called by CLI, although internally in the sdk it calls stack.outputs().

As mentioned previously I have issues testing this solution, so I invite you to test it yourself and collaborate on the final solution. I have found no relevant tests nor I can see a good way to unit test it, but I've updated the test workflow.

Reopened due to GH not recognizing the changes correctly in the original one after rebase.

@RobbieMcKinstry please verify it on your side, since there have been multiple changes in the project in the meantime.
Then let's either merge it or reject it, there is no point for it to be hanging here for months, while it is still a feature WE DO NEED and we keep using ugly workarounds as this is not available.

Hi @mikocot , I'm afraid I'm no longer a maintainer on this repository. I'll refer you to @justinvp or @simenandre who are able to review your pull request.

As a fellow community member, thank you for your contribution, and your patience. I apologize for having lost track of your PR when I was a maintainer. It was an oversight.

This looks reasonable to me. @simenandre any comments before we merge? My only thought is maybe this should have a test for it, but I'm not up to speed with how we're doing testing in this repo, so I'll defer that to you.

[mikocot]

@simenandre any comments? :)

Looks like something needs an update here, CI is complaining about:

I think output is missing from the enum of available commands.

to be honest it might have got out of date in the meantime 🙄

I fixed the previous conflict on the changelog, but now there is a new one. Can we please move on with this? @Frassle ?

[Frassle]

There we go :) Was a couple of minor things to fix up but merged now.

[mikocot]

great, we'll test it as soon as it's out, thanks

I pulled this down today and tried to use it in place of what I was previously running as preview - it doesn't seem to set the outputs the same way that preview does - is there something else special needed?

When running stack:
