Is your feature request related to a problem? Please describe.

The k8s 1.28 introduced "native sidecar" mode (init-container with restartPolicy: Always) https://kubernetes.io/blog/2023/08/25/native-sidecar-containers/.

The approach makes sure the sidecar starts/finishes before the application.

Describe the solution you'd like

Use the native sidecar for collector sidecar on k8s 1.28 and above.

I would like to give that a try.

Hey @frzifus, are you currently working on this task? If not, I'd be interested in contributing to it.

Any update on getting this support added? Or any known workarounds to get the new restartPolicy: Always included in the meantime?

We are running into this while using gcsfuse annotation which creates a native sidecar, and then the pods can't be terminated. Any estimated timelines for when/if the solution will be merged in? It appears to not have any movement on it for a few months.

Hey, I will try to get this ready on the weekend. :)
