The disk cache mode translates to various frontend and backend attributes for the qemu block layer. For the frontend device the 'writeback' parameter is used and provided as 'write-cache'. Implement this so that we can later switch to using -blockdev where we will not pass the cachemode directly any more. Signed-off-by: Peter Krempa <pkrempa@redhat.com>
