That's a good idea. I will create another patch to update the name so it's more descriptive.

Based on the following statement from GCE docs, the resources should not change as long as the machine type has been selected. "The number of virtual CPUs, amount of memory supported by the VM is dependent on the machine type selected"
The hardware information was added by following convention of existing slaves... I guess it would sort of indicate the performance of builder?
