one-core-peak: Reporting NVME features

This commit get some low-level features of NVME drives and report them.
It includes, temperature, apste, power state and submission & completion queues

A typical output looks like :
  nvme0n1: MODEL=Samsung SSD 970 EVO Plus 2TB FW=2B2QEXM7 serial=S59CNM0R417706B PCI=0000:01:00.0@8.0 GT/s PCIe IRQ=62 NUMA=0 CPUS=0-31
  nvme0n1: Temp:34 C, Autonomous Power State Transition: Enabled, PowerState:4, Completion Queues:32, Submission Queues:32
