Add virtio-blk by-id rules based on 'serial' attribute
Using virtio-blk serial attributes add rules to extract drive serial numbers and generate by-id links for the block device and partitions. With these rules added, we now see the following symlinks in disk/by-id % ls -al /dev/disk/by-id | grep vdb lrwxrwxrwx. 1 root root 9 Jun 1 22:09 virtio-QM00001 -> ../../vda lrwxrwxrwx. 1 root root 10 Jun 1 22:09 virtio-QM00001-part1 -> ../../vda1 Signed-off-by: Ryan Harper <ryanh@us.ibm.com>
