Walkthrough

This pull request updates the Proxmox Cloud Controller Manager chart version from 0.2.24 to 0.2.25. The deployment template is modified to introduce a new SERVICE_ACCOUNT environment variable that exposes the pod's service account name to the container. The cloud.go package is updated to read this environment variable at runtime, with a fallback to the existing hardcoded service account name if the variable is not set.
