Use a separate NODE_ADDRESS environment variable in the default value of
-kubelet-config-uri (instead of NODE_NAME that was previously used).
Also change the kustomize and Helm deployments to set this variable to
node IP address. This should make the default deployment more robust,
making it work in scenarios where node name does not resolve to the node
ip, e.g. nodename != hostname.
Change the configuration so that, by default, we use a dedicated
serviceaccount for topology-updater (similar to topology-gc, nfd-master
and nfd-worker).
Fix the templates so that the serviceaccount and clusterrolebinding are
only created when topology-updater is enabled (clusterrole was already
handled this way).
This patch also correctly documents the default value of rbac.create
parameter of topology-updater and topology-gc.
Make it possible to disable kubelet state tracking with
--set topologyUpdater.kubeletStateFiles="" as the documentation
suggests.
Also, fix the documentation regarding the default value of
topologyUpdater.kubeletStateFiles parameter.
Mount kubelet podresources socket on an independent path, not under
with the kubelet state directory. Otherwise container creation may fail
on mount creation if topologyUpdater.kubeletPodResourcesSockPath and/or
topologyUpdater.kubeletConfigPath Helm parameters are specified in a
certain way.
Implement a new generic type nodeListPropertyMatcher, a generic Gomega
matcher for matching basically any property of a set of node objects. We
will be using it for verifying labels, annotations, extended resources
and taints for now. This moves the tests in a more Gomega'ish direction,
leveraging code re-use and providing way more informative error messages
in case of test failures.
The patch adds a new eventuallyNonControlPlaneNodes helper assertion for
asserting all (non-control-plane) nodes in the cluster, intended to
replace the ugly simplePoll() helper function.
This patch implements a matcher for node labels and converts tests to
use it instead of the old checkForNodeLabels helper function.
This PR fixes the resync-period configuration option of the nfd-master.
In fact, previously, changes were not reflected in the nfd-master at
runtime. e2e tests are also implemented to make sure that the fix is
already working as expected.

Split out resolving of node name (of the node to be updated) into a
separate function. Makes it possible to add unit tests. Also. do
unconditional type casting in the handler functions – that shouldn't
fail unless there is a really serious internal inconsistency in the
codebase so it should be ok to panic.
Commit bfbc47f55e added a lot of those and
this patch tries to cover all that we missed there. Having .md suffixes
in references to internal files makes it convenient to browse the
document locally, just as text files as the references work correctly.
- kubelet_internal_checkpoint file is in /var/lib/kubelet/device-plugins not /var/lib/kubelet
fsWatcher doesn't watch dirs recursively
- e.Name returned from fsWatcher events is a full path not a basename

This PR adds a config option for setting the NFD API controller resync period.
The resync period is only activated when the NodeFeature API has been
enabled (with -enable-nodefeature-api).
