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).

Reject malformed extended resource dynamic capacity assignment
capacity should be in the form of domain.feature.element,
add logic at func filterExtendedResources to check if true or ignore
ExtendedResource, logging as an error.

Fix a a bug where nfd-master with NodeFeature API enabled would crash
when NodeFeatureRule objects were processed in the case where no
NodeFeature objects existed. This was caused by trying to insert values
into a non-initialized NodeFeatureSpec in the code.
This patch adds two safety measures to prevent that from happening in
the future. First, add a constructor function for the NodeFeatureSpec
type, and second, check for uninitialized object in the function
inserting new functions.
TODO: add unit tests for the API helper functions.
Make the nfd.node.kubernetes.io/feature-labels and
nfd.node.kubernetes.io/extended-resources annotations behave similary to
the taints annotation: only create the annotations if some labels or
extended resources are created.
