As an app dev, reviewing messages in `...workload get` output, I can see the fully qualified reference to the resource which emitted the error

[heyjcollins]

implementing this change is dependent upon updates to cartographer

There's an ask for them to add a field to their status which provides the fully qualified reference to the resource that's emitting any given message (error or otherwise) which the apps plugin displays in workload get output.

Description of problem

There's currently no obvious and deterministic way for a developer to associate a message that's displayed in the "Messages" section of workload get output with a specific resource. The absence of this association makes it difficult for a developer to troubleshoot errors when they occur.

Proposed solution

Include the fully qualified reference to the emitting resource in the message that's displayed.
