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.

This patch adds a new RPC method to configure QoS on bdev
at runtime.
For example:
set_bdev_qos_limit_iops Malloc0 20000 --> Enable QoS on this
block device with 20000 IOPS rate limiting.

Split bdevs now can be create using "create_split_bdev". To keep
backward compatibility, this call will not fail if base bdev is not
available yet instead will add base bdev name to its live configuration
and create splits when base bdev will be created (during examin
process).

Rather than requiring the 'verbose' flag as a parameter to
JSONRPCClient.call(), move it to the JSONRPCClient constructor so that
it can be set once.
This fixes the inconsistency between RPC method wrappers that passed
args.verbose and those that didn't; now, rpc.py -v works reliably for
all methods.
The JSONRPCClient.call() verbose parameter is maintained as well to
allow individual calls to be set to verbose if desired.
