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.

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
