The ephemeral containers API changed in 1.22. As a result, kubectl
debug (currently) cannot create ephemeral containers in clusters prior
to 1.22.
This change causes kubectl to retry the request using the old API when
it receives a specific error message from the server.
Instead of dynamically defaulting NodeRegistration.ImagePullPolicy,
which is common when doing defaulting depending on host state - e.g.
hostname, statically default it in v1beta3/defaults.go.
- Remove defaulting in checks.go
- Add one more unit test in checks_test.go
- Adapt v1beta2 conversion and fuzzer / round tripping tests
This also results in the default being visible when calling:
"kubeadm config print ...".
- provide tests for static policy allocation, when init containers
requested memory bigger than the memory requested by app containers
- provide tests for static policy allocation, when init containers
requested memory smaller than the memory requested by app containers
- provide tests to verify that init containers removed from the state
file once the app container started

Remove init containers from the state file once the app container started,
it will release the memory allocated for the init container and can intense
the density of containers on the NUMA node in cases when the memory allocated
for init containers is bigger than the memory allocated for app containers.

The idea that during allocation phase we will:
- during call to `Allocate` and `GetTopologyHints` we will take into account the init containers reusable memory,
which means that we will re-use the memory and update container memory blocks accordingly.
For example for the pod with two init containers that requested: 1Gi and 2Gi,
and app container that requested 4Gi, we can re-use 2Gi of memory.

Several plugins are removed in the v1beta2, but the legacy scheduler
config would still have the plugin configs of those removed plugins.
It was throwing raw byte data when those plugin configs are still in
place which will hard to read and understand.
Fix it by checking the removed plugin config before the validation of
the plugin args.

`distroless/base:latest` is a multi-arched image now, this will help the `kubemark` works properly
on the platforms other than `amd64`

1. create LB type svc with nodeport allocation set to false
1. create LB type svc with nodeport allocation unset
3. update LB type svc's nodeport allocation field

1. add AllocateLoadBalancerNodePorts fields in specs for validation test cases
2. update fuzzer
3. in resource quota e2e, allocate node port for loadbalancer type service and
exceed the node port quota
