3a1a3ff9d8 Introduce RequestEviction feature for evicting pods in background
When the feature is enabled each pod with descheduler.alpha.kubernetes.io/request-evict-only
annotation will have the eviction API error examined for a specific
error code/reason and message. If matched eviction of such a pod will be interpreted
as initiation of an eviction in background.

55a0812ae6 skip eviction when pod creation time is below minPodAge threshold setting (#1475)
* skip eviction when pod creation time is below minPodAge threshold setting

In the default initialization phase of the descheduler, add a new
constraint to not evict pods that creation time is below minPodAge
threshold.

Added value:

- Avoid crazy pod movement when the autoscaler scales up and down.

- Avoid evicting pods when they are warming up.

- Decreases the overall cost of eviction as no pod will be evicted
  before doing significant amount of work.

- Guard against scheduling. Descheduling loops in situations where
  the descheduler has a different node fit logic from scheduler,
  like not considering topology spread constraints.

* Use *time.Duration instead of uint for MinPodAge type

* Remove '(in minutes)' from default evictor configuration table

* make fmt

* Add explicit name for Duration field

* Use Duration.String()

bc60a058ef pod evictor: make it thread safe
Currently, all the plugins are run in a sequence.
No plugin executes evictions in parallel within.
Yet, there's no guarantee a future plugin (e.g. a custom one)
will not attemp to evict pods in parallel.
