### bdev_nvme



Added `num_io_queues` to `bdev_nvme_attach_controller` RPC to allow specifying amount

of requested IO queues.



### bdev



The NVMe bdev module supports multipath and improved I/O error resiliency.



The parameter `retry_count` of the RPC `bdev_nvme_set_options` was deprecated and will be

removed in SPDK 22.04, and the parameter `transport_retry_count` is added and used instead.



An new parameter `bdev_retry_count` is added to the RPC `bdev_nvme_set_options`.



New parameters, `ctrlr_loss_timeout_sec`, `reconnect_delay_sec`, and `fast_io_fail_timeout_sec`, are

added to the RPC `bdev_nvme_attach_controller`.



An new parameter `num_io_queues` is added to `bdev_nvme_attach_controller` RPC to allow specifying amount

of requested IO queues.



Added 'key_file' parameter to the 'rbd_register_cluster' RPC.  It is an optional parameter to

specify a keyring file to connect to a RADOS cluster.
