[StarCluster] StarCluster base AMI converted to C5 instance type

[Lyn Gerner]

Sergio, sounds like you're getting close.  /dev/xvdz is the real device
behind the link to it that some Linux variants create, which would be (the
perhaps more familiar to starcluster users) /dev/sdz. You will need to
update any reference to it from /dev/xvdz to /dev/nvme25n01. (In NVMe land,
"a" maps to 0 (zero), b maps to 1, ... , z maps to 25.)
