Yanbo Zhou 64ccd4b95b bdev: a new public function to get the I/O statistics of bdev 
Add a new function and its RPC caller. By using it, we can
get the statistics of all the bdevs or the specified bdev.

Meanwhile, with this patch, the open source tool 'sysstat/iostat'
can support for SPDK. The 'iostat' tool can call this function to
get the statistics of all the SPDK managed devices via the rpc
interface.
