lib/bdev: zoned info in get_bdevs RPC call 



Zoned bdev properties were added to the result of the get_bdevs RPC
call:
 - zoned: indicates whether the device is zoned or a regular
   block device
 - zone_size: number of blocks in a single zone
 - max_open_zones: maximum number of open zones
 - optimal_open_zones: optimal number of open zones

The "zoned" field is a boolean and is always present, while the rest is
only available for zoned bdevs.

Added `spdk_bdev_get_write_unit_size()` function for retrieving required number

New zone-related fields were added to the result of the `get_bdevs` RPC call:

 - `zoned`: indicates whether the device is zoned or a regular

   block device

 - `zone_size`: number of blocks in a single zone

 - `max_open_zones`: maximum number of open zones
