* Check if Pod matches inter-pod anti-affinity of other pod on node as part of NodeFit()
* Add unit tests for checking inter-pod anti-affinity match in NodeFit()
* Export setPodAntiAffinity() helper func to test utils
* Add docs for inter-pod anti-affinity in README
* Refactor logic for inter-pod anti-affinity to use in multiple pkgs
* Move logic for finding match between pods with antiaffinity out of framework to reuse in other pkgs
* Move interpod antiaffinity funcs to pkg/utils/predicates.go
* Add unit tests for inter-pod anti-affinity check
* Test logic in GroupByNodeName
* Test NodeFit() case where pods matches inter-pod anti-affinity
* Test for inter-pod anti-affinity pods match terms, have label selector
* NodeFit inter-pod anti-affinity check returns early if affinity spec not set
* 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
* use pod informers for listing pods in removepodsviolatingtopologyspreadconstraint and removepodsviolatinginterpodantiaffinity

* workaround in topologyspreadconstraint test to ensure that informer's index returns pods sorted by name

* pod anti-affinity check among nodes
* avoid pod equality check with UID field
also add node equality check with Name for short-cut
* add test case for anti-affinity violation among different node
* reduce ListPodsOnANode call
* fix old code
* apply gofumpt -w -extra
move klog/v2 import entry to bottom according to master code
