this image shows that retina targets are not resolved.

Platform (please complete the following information):

• OS: Windows 2022
• Kubernetes Version: [e.g. 1.22]
• Retina Version: Latest

Additional context
The root cause:

1. The retina win pods require annotation - prometheus.io/scrape = true but it is not seen.
2. Here is how retain win daemon-set looks like --
   kubectl describe daemonsets/retina-agent-win -n kube-system | findstr prometheus
   prometheus.io/port: 10093
   prometheus.io/scrape: true

kubectl describe pods/retina-agent-win-w2jdp -n kube-system | findstr prometheus

3. Scrape job looks for container name retina but retina windows pods look for retinawin
