Since the layer store was introduced, the level above the graphdriver now differentiates between read/write and read-only layers. This distinction is useful for graphdrivers that need to take special steps when creating a layer based on whether it is read-only or not. Adding this parameter allows the graphdrivers to differentiate, which in the case of the Windows graphdriver, removes our dependence on parsing the id of the parent for "-init" in order to infer this information. This will also set the stage for unblocking some of the layer store unit tests in the next preview build of Windows. Signed-off-by: Stefan J.
