Good that we did the rename on migration, as otherwise this might have
gone unnoticed.
The cleanest and simplest solution here might be to trigger the migration
only on boot, i.e. before rrdcached/pve-cluster starts up and can do any
RRD related stuff. While I'm not a huge fan of doing such migrations, it
is node local and only affects metrics and the old data is still there
in the renamed files, so no high fallout risk.
