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.

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.

with strict eviction policy the descheduler only evict pods if the pod

who request such a resource will be evicted.
