RHOAIENG-3458: Add a models command to the CLI

[devguyio]

Description

Add a models command that lists registered models from the model registry.

This PR is stacked on top of #222 .

How Has This Been Tested?

• Install models registry in your kubecluster following this video
• Port-forward port 8080 of the modelregistry-sample service in the namespace where you installed the model registry

  kubectl port-forward services/modelregistry-sample 8080

• From the cli directory, run the cli using go, the URL of the model registry is set via the env var MODEL_REGISTRY_URL which defaults to http://localhost:8080 .

  cd cli
  go run cmd/main.go

@grdryn thanks for the review. This PR was merged by mistake and a lot of the comments you mentioned were addressed in #234 . Basically, the models command was refactored in #234 to use the edge client and also be ready for merge.

So I suggest that you check that PR and consider it the proposed state of the models command? wdyt?

[grdryn]

Yeah, for sure, I plan to get around to looking at #234 soon too. I just figured that one would make more sense once I'd seen these earlier ones (that I know you'd mentioned had been merged accidentally).
