7ad44d04fc Enforce ReadWriteOncePod access mode during scheduling 
Check the PVC ref count on the node info cache to determine if a pod's
PVCs are in use. If they are and it is using ReadWriteOncePod, fail the
request.

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.

[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.
```
