Big refactor based on #4324 introducing a new drive layout - adding optimizations for Proxmox and old laptop drive layout . Also making it possible to boot from NVMe. Replacing blitz.datadrive.sh with blitz.data.sh - icluding the possibility to migrate an old ssd/nvme to a bigger one (copying complete data and blockchain). Lots of smaller changes.
