Provide container image for the pulp CLI

[lcarva]

Is your feature request related to a problem? Please describe.

I want to interact with a pulp server in my CI (Tekton). To do so, I'd like to use the pulp CLI. For that to happen I need a container image that contains the CLI.

Describe the solution you'd like
Either a new image under quay.io/pulp specifically for the CLI, or one of the existing images is extended to also include the CLI.

Describe alternatives you've considered
I could build my own image, but I think others could benefit from this as well.

It would be nice. So far I've built my own and using it in k8s as sidecar in pulp pod.
