Describe your problem

I have the same problem as #203 but approaching it differently. I'd like to be able to add any resource rather than just a gateway HTTP route object.

Though I'll take either solution at this point!

Describe your ideal solution

Based on the prior art found in a couple of charts I've seen, having the capacity to add objects out of the scope of the chart can be hugely beneficial.

Example of how this is used in the values of the grafana alloy helm chart here.
