Code Issues Proposed changes

Rename 'WindowsDriver' to 'WindowsISCSIDriver' 

This was the first Cinder Volume driver available on Windows,
for which reason it was simply called 'WindowsDriver'.

As we've added another driver available on Windows, the SMB driver,
this has caused quite some confusion.

For this reason, we're now renaming it to 'WindowsISCSIDriver'.
The new location will be:
    cinder.volume.drivers.windows.iscsi.WindowsISCSIDriver
