This will be used when generifying client-go: applying
ApplyConfigurations requires extracting their name, which is currently
done by accessing the corresponding public field directly; but that
can't be done with interfaces, which is what have to be used with
generics.

fixes for the memory manager tests by correctly restoring
the kubelet config after each test. We need to do before all
the related tests run, in order to make sure to restore the
correct values.
Add more debug facilities to troubleshoot further failures.

e2e_node test depend on very specific shared state (node state).
Pod leakages between tests oftentimes cause the test preconditions
to be silently corrupted, causing hard to debug CI failures.
Use the new facility to annotate pods with test owner (= the
test code which created the test) to help debug these failures.
For more context, please check the conversation in #123468

e2e_node test depend on very specific shared state (node state).
Pod leakages between tests oftentimes cause the test preconditions
to be silently corrupted, causing hard to debug CI failures.
We add the option to add an annotation to pods which records
the code line (source code:line) which triggered the pod creation,
so it becomes easier to track which test needs better cleanup.
The relevant e2e framework code is used in all the e2e suites,
so to minimize any unwanted consequences we make the feature
opt-in, planning to enable it initially (and likely only)
in the e2e_node tests.

**Problem:** When a Pod fails to run due to kubelet-side admission checks, the
v1.Event objects emitted looks like these:
Reason="NodeAffinity" Message="Predicate NodeAffinity failed"
Reason="NodeName" Message="Predicate NodeName failed"
Reason="NodePorts" Message="Predicate NodePorts failed"
**Solution:** Expose human-readable predicate description in the failure
so that kubelet submits an Event with this description, such as:
Reason="NodeAffinity" Message="Predicate NodeAffinity failed: node(s) didn't match Pod's node affinity/selector"
Reason="NodeName" Message="Predicate NodeName failed: node(s) didn't match the requested node name"
Reason="NodePorts" Message="Predicate NodePorts failed: node(s) didn't have free ports for the requested pod ports"
The claim parameter key didn't include the namespace of the claim. In the case
where two namespaces used the exact same parameter reference, the "too many
generated parameters" case got triggered incorrectly and lookup could have
returned an object from the wrong namespace.
Found while running the E2E tests in parallel:
message: 'running PreFilter plugin "DynamicResources": multiple generated claim
parameters for ConfigMap. dra-8794/parameters-3 found: [dra-4729/parameters-4
dra-7328/parameters-4 dra-8794/parameters-4 dra-3402/parameters-4 dra-6156/parameters-4
dra-1839/parameters-4 dra-7434/parameters-4 dra-6504/parameters-4]'
After the introduction of v1beta4 if the user inputs the old
v1beta3 discovery timeout the value is ignored. Fix that
by introducing a conversion to v1beta4.
