PDB with an empty selector `{}` is selecting all the pods in a namespace.
But, during the `drain`, all the pods are getting evicted which is not expected.
This change should fix the issue and honor the pdb before evicting the pods.

Instead of numerating all the etcd endpoints known by apiserver, we will
group them by purpose. `etcd-0` will be the default etcd, `etcd-1` will
be the first resource override, `etcd-2` will be the second override and
so on.
These don't belong in pkg/proxy/util; they involve a completely
unrelated definition of proxying.
Since each is only used from one place, just inline them at the
callers.
The ipallocator for the new IPAddress object use the golang big.Int
library for some math operations, like adding an offset to an IP
address.
We use the bytes array to convert between big.Int and IP addresses,
however, IP addresses are always represented as 4 or 16 bytes arrays.
Big int bytes representations just return the byte array until the
most representative number, this requires that we need to prepend
these extra bytes for IPs with leading zeros.

This touches cases where FromInt() is used on numeric constants, or
values which are already int32s, or int variables which are defined
close by and can be changed to int32s with little impact.

add a new ClusterIP allocator that uses the new IPAddress API resource
and an informer as the backend, instead a bitmap snapshotted on etcd.

The pod_logs subsystem was inadvertently made redundant in the following
kube-apiserver metrics:
- kube_apiserver_pod_logs_pods_logs_backend_tls_failure_total
- kube_apiserver_pod_logs_pods_logs_insecure_backend_total
To safely rename them, it is required to deprecate them in 1.27 whilst
introducing the new metrics replacing them.

1. Define ContainerResizePolicy and add it to Container struct.
2. Add ResourcesAllocated and Resources fields to ContainerStatus struct.
3. Define ResourcesResizeStatus and add it to PodStatus struct.
4. Add InPlacePodVerticalScaling feature gate and drop disabled fields.
5. ResizePolicy validation & defaulting and Resources mutability for CPU/Memory.
6. Various fixes from code review feedback (originally committed on Apr 12, 2022)
