@mortent The cli-utils release 0.28.0 is available. Could you please update this PR?

[mortent]

@Liujingfang1 This is ready now. It updates kpt to use the latest version of cli-utils, however it does not add the functionality to add the apply status to the RG resource.

@sdowell This makes some changes to how we handle the flags. I see that you made some changes here to make the autocomplete work (#2631). Is there any automatic tests for this or can you tell me how I can verify that I haven't broken anything?

In the future, it would be nice for cli-utils updates to include a feature/fix highlights with user-facing features/fixes, so they make it to the kpt change log.

Here's some highlights for this one (v0.27.0 -> v0.28.1):

• Add Actuation & Reconciliation status to the ResourceGroup inventory status.
• Collect and report validation errors from all objects at the same time, not just the first one to fail.
• Disable the broken namespace inference feature in apply-time-mutation.
  The user must specify the namespace, for namespace-scoped source objects,
  otherwise a validation error will be returned.
• Stop returning timeout/cancellation as a resource error.
• Make CyclicDependencyError edge ordering stable/consistent.
• Update Kubernetes libraries to v1.23.2
• Remove legacy support for multiple inventory objects with the same inventory id.
