Steve Baker a6e0bf83db Add a growvols utility for growing LVM volumes ... There is currently no automated way of growing LVM volumes on boot like single partition images do with their growroot mechanism. This lack likely contributes to LVM not being widely used on VM and baremetal workloads, since growing to the full disk requires workload knowledge to determine which volumes to grow and by what amount. The growvols element contributes a growvols python script which can be run on firstboot (via systemd or cloud-init) or manually via automation such as ansible. It is also an interactive script which displays the full list of modifying commands before prompting for confirmation to run them all. By default the script will grow the root volume, but arguments allow any volume to grow by a specified amount, or a percentage of the available disk space.
