[FEA]: Web proxy support for helm chart

[jeffoxenberg]

Is this a new feature, an improvement, or a change to existing functionality?

Improvement

How would you describe the priority of this feature request

Low (would be nice)

Please provide a clear description of problem this feature solves

Some corporate self-hosted environments are behind a web proxy. The NIM Operator has a spec.proxy configuration but this is not exposed in the RAG helm chart, which causes the cache job to fail in proxied environments. Exposing spec.proxy in the helm chart's NIMCache would allow the pod to connect to the internet and pull the model.

Feature Description

As a deployer of the RAG helm chart, I want to be able to specify the web proxy for the NIM Cache to use, so that it can successfully reach the internet and download a model.

Describe your ideal solution

The helm chart adds values to configure http/https/noproxy variables and uses these in the NIMCache tempalte.

Describe any alternatives you have considered

I have written a kyverno policy that mutates the NimCache CR in my environment but it would be good if the spec.proxy configuration was exposed in the chart itself.
