Since #2801 we support native sidecars via feature gate.
This featuregate can only be used on k8s 1.29 or higher. On OpenShift OLM does not support setting custom feature gates. Making it impossible to enable this by default soon. (Within the next two years)

We need to discuss with the SIG if we want to add another deployment mode. Extending `deployment`, ` daemonset` and `sidecar` by `native-sidecar`. 

In that case the user can always choose and we can reject the manifest if the k8s version does not support native sidecars.

OpenShift 4.16 is based on k8s 1.29
