Adding kubernetes sub command using Kubernetes Explorer endpoints

[deejgregor]

I have been experimenting with an addition to pup that adds kubernetes subcommands for listing and retrieving objects. It uses the Kubernetes Explorer endpoints and seems like a fairly straightforward addition. I’m curious if this would be a contribution that might be accepted.

This would be fairly valuable to us because we have a few dozen clusters and there is no existing Datadog APIs (outside of what is used by the UI) to list and retrieve Kubernetes objects. We can get some information from metrics, traces and DDSQL but none of those expose the YAML for objects, which we would like to be able to access programmatically for all of our clusters. For example, after last week’s AWS us-east-1 outage, we had some StatefulSets that didn’t have pods spread across AZs as widely as we’d like, and being able to programmatically examine pods would make this analysis pretty straightforward (we can get close with metrics, but still have some gaps).

(FYI: I might also have a similar request for CNM data)
