As RHEL-10, and related OS projects (CentOS, RockyLinux, and AlmaLinux), need specific x86_84 machine levels, in this case x86_64-v3, It's helpful to see which CPUFlags are present in a given node and which version of QEMU is available. This adds a small tool to list the CPUFlags needed and those found. There are a few tools that will can do similar things but I didn't find one that covered what we need.
