Provide an additional way to request the block layer to prioritize foreground I/O over background I/O. This patch prepares for tests with the mq-deadline I/O scheduler. While CFQ and BFQ support a "weight" cgroup attribute, the mq-deadline scheduler does not. The mq-deadline I/O scheduler only supports the I/O priority class for differentiating I/O priorities. The io.prio.class attribute is declared optional since this attribute only exists if CONFIG_BLK_CGROUP_IOPRIO != n in the kernel configuration.
