Description

As described here: https://github.com/kairos-io/kairos/issues/3651#issuecomment-3280239643

we need to read the desired mount path from the NodeOp resource (NodeOpUpgrade too? or maybe not, since we are the ones defining the script there). Then we need to also set the environment variable for the Pods so that the kairos-agent knows where the host dir is mounted: https://github.com/kairos-io/kairos-agent/blob/487fc15f233e135e4bdd37954602b3c3ae45e7f6/pkg/utils/k8s/common.go#L12

Contributor guide

Research direction
Inspect the Kairos operator code to find where host directory mounts are configured. Add a new field to the NodeOp resource for the desired mount path. Then set the environment variable for the Pods so the kairos agent knows the host dir mount path.
