b6c75bee15 Remove balanced attached node volumes 
kubernetes#60525 introduced
Balanced attached node volumes feature gate to include volume
count for prioritizing nodes. The reason for introducing this
flag was its usefulness in Red Hat OpenShift Online environment
which is not being used any more. So, removing the flag
as it helps in maintainability of the scheduler code base
as mentioned at kubernetes#101489 (comment)

63d1237102 Fix Node Resources plugins score when there are pods with no requests 
Given that we give a default CPU/memory requests for containers that don't provide any, the calculated usage can exceed the allocatable.

Merge pull request #101467 from ingvagabund/noderesources-replace-IsScalerResourceName-with-nodeinfo-allocatable-scalar-resource-presence 
noderesource: node info already knows which resources are scalar

7286f9712a pkg/scheduler: drop Resource.ResourceList() method 
The method is used only for testing purposes. Given Resource data type
exposes all its fields, any invoker of ResourceList that is still
using the method outside of kubernetes/kubernetes can still either
copy paste the original implementation or implement a custom method
that's converting resources into proper Quantity data type.

Given the hugepage resource is a scalar resource, it's sufficient
the underlying code under fit_test.go to take into account any
extended resources. For predicate_test.go, the hugepage
resource does not play any role as the General predicates test cases
does not set any scaler resource at all.

Additionally, by removing ResourceList method, pkg/scheduler/framework
can get rid of dependency on k8s.io/kubernetes/pkg/apis/core/v1/helper.

11d6576f83 noderesource: node info already knows which resources are scalar 
NodeInfo.Allocatable.ScalarResources already knows which resources
are scaler. Also, if the resource name is not present,
it's pointless to compute score for a resources the node can not allocate
since nodeInfo.Allocatable.ScalarResources[resource] is zero for the case.
And both leastRequestedScore and mostRequestedScore returns 0 score
for nodes with zero allocatable resource.
The balancedResourceScorer deals only with CPU and memory which
are not scalable resources.
