Code Issues Proposed changes

Update git submodules 

* Update os-brick from branch 'master'
  to 9b0a91039a86af9e1a551cc3898e218759e0ef79
  - Merge "rbd Windows support"
  - rbd Windows support
    
    Ceph 16 (Pacific) is going to support mounting RBD images on
    Windows[1].
    
    This change provides a simplified RBD connector for Windows.
    
    The Windows RBD connector is very similar to the Linux one.
    There are a few main differences though:
      * the Ceph python bindings are not available on Windows yet, so
        we'll always do a local mount. Besides, Hyper-V cannot use
        librbd directly, so we'll need a local mount anyway.
      * The device names aren't handled in the same way. On Windows,
        disk names such as "\\.\PhysicalDrive1" are provided by
        the OS and cannot be explicitly requsted.
      * under high load, the disk might not become available immediately,
        we're adding a few checks when mapping the image.
      * rbd-wnbd provides a "show" command, which we're going to use
        in order to retrieve mounted disk paths
      * rbd-wnbd provides a "hard-disconnect" option, used when forcefully
        disconnecting volume. By default, WNBD waits for the Windows
        storage PnP stack before removing the attachment (e.g. waiting for
        open handles, unflushed data, pending IO, etc).
    
    We're adding a mixin class meant to avoid duplicating code between
    the Linux and Windows RBD connectors.
    
    Integration testing will be covered by the existing Windows CI.
