06cab8e2aa fix: pod resource calculation to consider native sidecars 
previously, descheduler code had copied an old version of PodRequestsAndLimits which does not consider native sidecars
it will now rely on resourcehelper libs, which will continue to get upstream updates

d9d6ca64e9 feat: enable pod protection based on storage classes 
this commit introduces a new customization on the existing PodsWithPVC
protection. this new customization allow users to make pods that refer
to a given storage class unevictable.

for example, to protect pods referring to `storage-class-0` and
`storage-class-1` this configuration can be used:

```yaml
apiVersion: "descheduler/v1alpha2"
kind: "DeschedulerPolicy"
profiles:
- name: ProfileName
  pluginConfig:
  - name: "DefaultEvictor"
    args:
      podProtections:
        extraEnabled:
        - PodsWithPVC
        config:
          PodsWithPVC:
            protectedStorageClasses:
            - name: storage-class-0
            - name: storage-class-1
```

changes introduced by this pr:

1. the descheduler starts to observe persistent volume claims.
1. a new api field was introduced to allow per pod protection config.
1. rbac had to be adjusted (+persistentvolumeclaims).

3a608a590a feat(eviction): add annotations to eviction requests for observability 
Although eviction requests (policy/v1) are not persisted long term,
their API still implements the full metav1.ObjectMeta struct. While
name and namespace refer to the pod being evicted, eviction requests
can still carry annotations.

This change adds annotations to descheduler-initiated evictions,
including the requester, reason, and the strategy or plugin that
triggered them.

While these details are already logged by the descheduler, exposing them
as annotations allows external webhooks or controllers to provide
clearer context about each eviction request, both for tracking and
prioritization purposes.

7380aa6e0a DefaultEvictor: introduce no-eviction policy 
NoEvictionPolicy dictates whether a no-eviction policy is prefered or mandatory.
Needs to be used with caution as this will give users ability to protect their pods
from eviction. Which might work against enfored policies. E.g. plugins evicting pods
violating security policies.

we have been carrying these no-op for quite a while now. we should only
set defaults when they are different from what they are being provided
