command: "terraform web" command

[apparentlymart]

This is a small utility command to help bridge from Terraform CLI to the Terraform Cloud web UI.

When used in a configuration that has a Terraform Cloud configuration, it will ask the Cloud integration for a URL that represents a requested "target object" and then try to open that URL in a web browser. If launching a browser isn't possible for any reason then it'll just print out the URL it would've opened to, so that the user can hopefully still follow the link from their terminal or copy it into their browser's URL bar.

• terraform web opens the main landing page for the currently-selected workspace
• terraform web -latest-run opens the run details page for the most recent run in the currently-selected workspace
• terraform web -run=ID opens the run details page for the specified run ID

I imagine there are other "target objects" that could be useful to support here later too, but since each one of these imposes a new compatibility constraint on Terraform Cloud's web UI (because of the hard-coded URL patterns and the need to keep offering a suitable page to link to) I've kept this minimal to start, mainly just to have something to play with and gather feedback on.

Draft CHANGELOG entry

NEW FEATURES:

• terraform web: Open pages related to the current working directory in the Terraform Cloud web UI.

Our Terraform Cloud colleagues have indicated a preference to have most Terraform Cloud-specific functionality live under a terraform cloud subcommand whose implementation lives in a separate plugin that can evolve independently of Terraform CLI, since Terraform Cloud is a SaaS product and thus evolves on quite a different rhythm to Terraform CLI itself.

With that in mind, I think functionality like what I implemented here would be more at home in their plugin, so that they can add new possibilities to the plugin and have them become available for use more-or-less immediately, rather than having to wait for a subsequent Terraform CLI release.

Therefore I'm going to close this. Some of the early infrastructure for the separate terraform cloud subcommands was added in #33463, and I expect further work on that will continue in other PRs.
