9f95b7b18c unittests: Fixes unit tests for Windows (part 3) 
Currently, there are some unit tests that are failing on Windows due to
various reasons:

- paths not properly joined (filepath.Join should be used).
- Proxy Mode IPVS not supported on Windows.
- DeadlineExceeded can occur when trying to read data from an UDP
  socket. This can be used to detect whether the port was closed or not.
- In Windows, with long file name support enabled, file names can have
  up to 32,767 characters. In this case, the error
  windows.ERROR_FILENAME_EXCED_RANGE will be encountered instead.
- files not closed, which means that they cannot be removed / renamed.
- time.Now() is not as precise on Windows, which means that 2
  consecutive calls may return the same timestamp.
- path.Base() will return the same path. filepath.Base() should be used
  instead.
- path.Join() will always join the paths with a / instead of the OS
  specific separator. filepath.Join() should be used instead.

fd08d47d8b cleanup: move scheduler tests to use PodWrapper 
Move to use testing PodWrapper where applicable to
reduce duplicating pod creation code and shorten

32c18a3479 Adding StorageInfoLister to SharedLister 
This change creates a StorageInfoLister interface
and have it under scheduler SharedLister.

The initial StorageInfoLister interface has a
IsPVCUsedByPods which returns true/false depending on
whether the PVC (keyed by namespace/name) has at least
one scheduled pod using it.

In snapshot real implementation, add a usedPVCSet
key by PVC namespace/name which contains all PVCs
that have at least one scheduled pod using it.
During snapshot update, populate this set based on
whether the PVCRefCounts map for node(s) have been
updated since last snapshot.

0f4d0660a7 kube-scheduler: finish conversion to structured logging 
Thanks to support for multi-line string values we can now also convert
these remaining klog.Info calls without making the output unreadable
in text format.

The debug log messages intentionally don't get changed to ensure that
developers looking for it still find it.

The output now looks like this:
