This change is prototyping how using the native LVM device paths reported by device mapper could work together with lvm controlled filesystem resizing in order to run controller-only online/offline volume expansion.
Note that the current design breaks with existing TopoLVM because it switches from using the TopoLVM device directory to using the lvm owned device paths (so TopoLVM no longer renames the devices).
I want to drive a POC here so that I can further debug and showcase how much more efficient we could be regarding dealing with device paths, lvm compatibility and the CSI spec.
