Node-feature-discovery was migrated into a new repository under the
kubernetes-sigs organization in Github (#175). Related to the migration,
the final container image registry/repo hasn't been dediced yet (#177) –
for this release we still use the old repo.

Major changes
- Split NFD into client and server (#209)
- Changes in labels:
  - NFD label namespace was changed to 'feature.node.kubernetes.io/' (#176)
    - 'nfd-' prefix was dropped from all feature labels
    - NFD version label
      (feature.node.kubernetes.io/node-feature-discovery.version) was
      replaced by an annotation (nfd.node.kubernetes.io/version)
  - network SRIOV labels were changed (#173):
    - 'network-sriov' -> 'network-sriov.capable'
    - 'network-sriov-configured' -> 'network-sriov.configured'
  - selinux detection was moved to kernel feature source
    - 'selinux' -> 'kernel-selinux.enabled'
  - cpuid, pstate and RDT labels moved under cpu feature source (#217)
    - 'cpuid-<cpuid flag>' -> 'cpu-cpuid.<cpuid flag>'
    - 'pstate-turbo' -> 'cpu-pstate.turbo'
    - 'rdt-<rdt feature>' -> 'cpu-rdt.<rdt feature>'
- Support for config file (#169). Currently with three configurable
  feature sources i.e. cpu (#224), kernel (#157) and pci (#168)
- Support for non-binary labels, with arbitrary values other than plain
  'true'
- PCI device detection (#168)
- Kernel version detection (#157)
- Kernel config option detection (#146)
- Support for custom feature-detector hooks (#144)
- Support OS version detection (#149, #211)
- Detection of hardware multithreading, such as Intel Hyper-Threading
  Technology (#147)
- Arm64 support for CPUID detection (#194)
- Validation of feature label names and values (#199, #219)
- Detection of NVDIMM devices (#214)
- Get labels by reading from file in 'local' source (#228)
- Detection of Intel SST-BF (Speed Select Technology - Base Frequency) (#235)
- Make it possible to create feature labels in non-default namespace
  (#231). Currently possible for using the local source (hooks and files).

Miscellaneous
- Template specs converted from json to yaml
- Documentation updates and fixes
