4053010dd9 Make the kernel feature source configurable 
Adding two config options:
- kernel config file to read
- kconfig options that are detected

ce129aef88 Implement kernel config detection 
This implementation only detects kconfig options ("NO_HZ", "NO_HZ_IDLE",
"NO_HZ_FULL" and "PREEMPT"). The corresponding node labels will be
  node.alpha.kubernetes-incubator.io/nfd-kernel-config.<option name>

Currently, only bool and tristate (i.e. '=y' or '=m') kernel config
options are supported. Other kconfig types (e.g. string or int) are
simply ignored. If the kconfig flag is set to '=y' or '=m', the
corresponding node label will be present and it's value will be 'true'.

86947fc16b Implement kernel version detection 
Add a new 'kernel' feature source, detecting the kernel version. The
kernel version is split into multiple labels in order to make this more
usable in label selectors. Kernel version in the format X.Y.Z-patch will
be presented as
  node.alpha.kubernetes-incubator.io/nfd-kernel-version.full=X.Y.Z-patch
  node.alpha.kubernetes-incubator.io/nfd-kernel-version.major=X
  node.alpha.kubernetes-incubator.io/nfd-kernel-version.minor=Y
  node.alpha.kubernetes-incubator.io/nfd-kernel-version.revision=Z

The '.full' label will always be avaiable. The other labels if these
components can be parsed from the kernel version number.
