This started as a small effort to simplify the usage of "ready" channel
in nfd-master. It extended into a wider simplification/unification of
the channel usage.
APIVersion and Kind are empty in the returned namespace object
and need to be set explicitly.

This change is part of an effort to remove the pkg/apihelper package.
GetKubeconfig is useful helper functionality shared accross the codebase
so move it into a "safe" location.
We need to parse kubeconfig (and initialize the apihelper) even with
-no-publish as the PodResourcesScanner accesses the k8s API even if
we're not publishing/updating NRTs.
The nfd-topology-updater has state-directories notification mechanism
enabled by default.
In theory, we can have only timer-based updates, but if the option
is given to disable the state-directories event source, then all
the update mechanism is mistakenly disabled, including the
timer-based updates.
The two updaters mechanism should be decoupled.
So this PR changes this to make sure we can enable just and only
the timer-based updates.

NFD is only detecting policy and scope of Topology Manager when NRT object doesn't exist.
This means that topologyManagerScope and topologyManagerPolicy attributes won't be updated
even if kubelet config was changed to use other TopologyManager policy and scope.

Drop the KlogDump helper in favor of klog.InfoS. However, that patch
introduces a new DelayedDumper() helper to avoid processing
(marshalling) of object unless really evaluated by the logging function.
Access to the kubelet state directory may raise concerns in some setups, added an option to disable it.
The feature is enabled by default.

When a message received via the channel,
the main loop updates the `NodeResourceTopology` objects.
The notifier will send a message via the channel if:
1. It reached the sleep timeout.
2. It detected a change in Kubelet state files

On different Kubernetes flavors like OpenShift for exmaple,
the Kubelet state directory path is different. make it configurable
for maximum flexability.
