[NGINX]: DNS Lookup of multiple ingress pods via headless service

[toms-place]

Integration Name

Nginx [nginx]

Dataset Name

stubstatus

Integration Version

1.24.1

Agent Version

8.14.3

OS Version and Architecture

Debian GNU/Linux 11 (bullseye) - 6.1.0-0.deb11.21-cloud-amd64

User Goal

I would like to use a headless service to scrape the stubstatus of all my ingress nginx instances individually.

Existing Features

Currently I would need to add each host individually, or use a service, which load balances in a round-robin fashion.
Adding each host is no option, because the pod IPs will change from time to time.

What did you see?

Data ingest is working fine for a single instance.

Anything else?

If there is an easy option to instruct the agent to use a headless service and scrape each IP resolved via DNS, I am happy to create a PR for it.
If not, I think this is a general request for all integrations.

I started to create a PR to add custom configuration for the nginx integration. This would enable us to use it on nodes where ingress nginx is running and scrape the metrics from the pod IPs directly. Therefore the headless service feature would not be needed anymore.
