Fix Node Resources plugins score when there are pods with no requests

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.

383ce85649 [scheduler] avoid comparing function pointers in unit tests 
PluginFactory is a function that returns a plugin. We have been
comparing these functions in unit tests and it has worked so far, but
starts to fail in gotip/master.

Note from the golang team:
```
Func values are incomparable. It is true that you could get the PC
through reflection but it is still not expected to be compared. PCs
can change due to inlining, wrappers, etc., depending on the
compiler's details, which is subject to change.
```

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.
