1974c12e0f Extend plugin's New with a context.Context
The new context.Context can be later used for passing a contextualized
logger. Or, other initialization steps that require the context.

35a7178df6 feat: introduce strict eviction policy
with strict eviction policy the descheduler only evict pods if the pod
contains a request for the given threshold. for example, if using a
threshold for an extended resource called `example.com/gpu` only pods
who request such a resource will be evicted.

98e6ed6587 chore: log average and assessed thresholds
when calculating the average an applying the deviations it would be nice
to also see the assessed values.

this commit makes the descheduler logs these values when using level 3.

54d0a22ad1 chore: comment the code and simplify some things
this commit comments the low and high utilization plugins. this also
simplifies a little bit where it was possible without affecting too
much.

utilization plugins. both high and low plugins are affected by this
change.

5bf11813e6 lownodeutilization: evictionLimits to limit the evictions per plugin
In some cases it might be usefull to limit how many evictions per a
domain can be performed. To avoid burning the whole per descheduling
cycle budget. Limiting the number of evictions per node is a
prerequisite for evicting pods whose usage can't be easily subtracted
from overall node resource usage to predict the final usage. E.g. when a
pod is evicted due to high PSI pressure which takes into account many
factors which can be fully captured by the current predictive resource
model.

d1c64c48cd nodeutilization: separate code responsible for requested resource extraction into a dedicated usage client
Turning a usage client into an interface allows to implement other kinds
of usage clients like actual usage or prometheus based resource
collection.

bb5930eb21 Improve PodEvictor observability through EvictOptions (#1349)
* feat: profile name for pods_evicted metric

Support new label "profile" for "pods_evicted" metric to allow
understand which profiles are evicting more pods, allowing better
observability

* refactor: evictoptions improved observability

Send profile and strategy names for EvictOptions, allowing Evictors to
access observability information

* cleanup: remove unnecessary evictoption reference

* feat: evictoptions for nodeutilzation

Explicit usage of options when invoking evictPods from the helper
function from nodeutilization for both highnodeutilization and
lownodeutilization
