Hui Zhu f6511471d4 block: Add cache-related options for block devices
Add block_device_cache_set, block_device_cache_direct and
block_device_cache_noflush.
They are cache-related options for block devices that are described in
https://github.com/qemu/qemu/blob/master/qapi/block-core.json.
block_device_cache_direct denotes whether use of O_DIRECT (bypass the host
page cache) is enabled.  block_device_cache_noflush denotes whether flush
requests for the device are ignored.
The json said they are supported since 2.9.
So add block_device_cache_set to control the cache options set to block
devices or not.  It will help to support the old version qemu.

Fixes: #956
