Feature Request: k8s-infra support for collection application-level prometheus metrics

[jkgeyti-cogna]

The k8s-infra helm chart is convenient for cloud customers who do not wish to self-host the full stack, but unlike the signoz chart, the k8s-infra chart doesn't run an prometheus metrics collector for collecting pod metrics by default.

I had a conversation with @srikanthccv who came up with a solution using the override below, which seems like a sensible thing to be able to toggle on or off as part of the template, instead of having to override it like this.

Thanks for a great product.
