Description

Power outages can lead to empty cmeta files on XFS (KUDU-2195), and sometimes all replicas are affected. By checking the ksck output and the WAL dumps it's possible to reconstruct how the cmeta should look like, except for the voted_for part, but that isn't required to be able to bootstrap a tablet, so a tool to manually create a cmeta file would be useful to recover such tablets.
