[Epic] "Virtual" resources ("views", "subresources") support

[lunaris]

Project: https://github.com/orgs/pulumi/projects/289/views/1

There are a number of use cases where a provider wants to offer resources that share traits of both custom and component resources:

• Component-like -- the resource wants to report children/subresources (as can be done in Construct)
• Custom-like -- the resource wants to be subjected to the CRUD lifecycle and observe Create, Update and so on.

Presently, it is neither possible for a Constructed component to observe the CRUD lifecycle, nor for a custom resource to register children. This epic is about investigating the latter, in which a custom resource may return "virtual" resources as part of its CRUD operations. These resources are not "real" in the sense that they themselves do not receive dedicated lifecycle method calls, but they are still tracked by the engine, reported in diffs and CLI views, and visible in state, for instance.

[Epic] "Virtual" resources ("views", "subresources") support status update
Status: ON_TRACK

Last week

• Continued to make progress on the views implementation in the engine. I was originally aiming to have an initial working implementation in a CLI release (behind feature flag) late last week, but it's slipped into early this week.
• Opened a couple tiny PRs to start landing the changes:
  • Views: protobuf changes #19349
  • Views: Adopt on plugin.Provider #19408

This week

• Ship working implementation (behind feature flag) early this week
  • More testing
  • Investigate issue I was hitting validating view steps & update plans
• The rest of the week, shift gears and focus primarily on making use of it in the TF module repo
• Checkpoint version bump
• CLI UX around --target, --exclude, etc.

This week

• Monday, finishing up basic functionality (create/update done; addressing a problem with even order and deletes)
• Integrate with tf modules
• Address any issues that come up as part of that
