Virtual Kubelet: Persistent Volumes and Persistent Volume Claims

[MbolotSuse]

Currently, Persistent Volumes and Persistent Volume Claims only exist within the virtual cluster. Since pods in shared mode run in the host cluster, the PVs and PVCs are not usable by the workloads. To get them usable by the workloads, they need to exist in the host cluster.

A simple sync will likely not work for this issue. Simply sync'ing the volumes might result in duplicated storage (for cloud volumes like EBS). We likely will need to add a proxy in-front of the k3s server pod to ensure volumes are only created in the Host Cluster.
