Node Feature Discovery

Is a new plugin that has been recently introduced as part of the Luigi operator that will discover features at the host level like SRIOV enabled, kernel version, swap, ram, cpu, disks and others and create labels on the nodes with those key-values on each node on the cluster.

As an example, here are some feature labels that have been added to an SRIOV node automatically by NFD plugin

labels:...  feature.node.kubernetes.io/cpu-cpuid.AESNI: "true"  feature.node.kubernetes.io/cpu-cpuid.AVX: "true"  feature.node.kubernetes.io/cpu-cpuid.IBPB: "true"  feature.node.kubernetes.io/cpu-cpuid.STIBP: "true"  feature.node.kubernetes.io/cpu-cpuid.VMX: "true"  feature.node.kubernetes.io/cpu-hardware_multithreading: "true"  feature.node.kubernetes.io/cpu-pstate.turbo: "true"  feature.node.kubernetes.io/iommu-enabled: "true"  feature.node.kubernetes.io/kernel-config.NO_HZ: "true"  feature.node.kubernetes.io/kernel-config.NO_HZ_FULL: "true"  feature.node.kubernetes.io/kernel-version.full: 3.10.0-1127.18.2.el7.x86_64  feature.node.kubernetes.io/kernel-version.major: "3"  feature.node.kubernetes.io/kernel-version.minor: "10"  feature.node.kubernetes.io/kernel-version.revision: "0"  feature.node.kubernetes.io/memory-numa: "true"  feature.node.kubernetes.io/network-sriov.capable: "true"  feature.node.kubernetes.io/network-sriov.configured: "true"  feature.node.kubernetes.io/pci-0300_1a03.present: "true"  feature.node.kubernetes.io/storage-nonrotationaldisk: "true"  feature.node.kubernetes.io/system-os_release.ID: centos  feature.node.kubernetes.io/system-os_release.VERSION_ID: "7"  feature.node.kubernetes.io/system-os_release.VERSION_ID.major: "7"
