To enable the SPDK NVMe-oF target discovery controller to act as a DDC, this patch added support for mDNS Pull Registration Requests. A DDC may respond to mDNS queries for the service name of "._nvme-disc._<protocol>.local." This patch covers the sending part of the mDNS message.

SPDK provides a histogram function about io delay in the bdev layer,

Therefore, a new rpc method is added to control the opening or

nvmf: per-host namespace masking

This patch introduces namespace masking for NVMe-over-fabrics
targets by allowing to (dynamically) add or remove hosts for a given
namespace on a given subsystem. A host can only
perform operations to a namespace it has been given access.

To preserve current behavior all namespaces are automatically visible.
To control visibility on a per-host basis, the nvmf_subsystem_add_ns RPC
shall be called with "--no-auto-visible". We introduce two new
RPC calls:
- nvmf_ns_add_host <subsysNQN> <NSID> <hostNQN>
- nvmf_ns_remove_host <subsysNQN> <NSID> <hostNQN>
These RPCs apply both to existing and future controllers for the given
subsystem/hostnqn pair.

The list in spdk_nvmf_ns is used to keep track of hostNQNs
which controllers should be attached on connect.

The visible_ns array in spdk_nvmf_ctrlr is used for fast lookup
to check whether a NSID is visible on command execution.

lib/iscsi: Add RPC method iscsi_get_stats

In a production environment, the iscsi_get_connections RPC method is
commonly used to monitor the number of SPDK connections. It is often
necessary to issue an alarm when there are too many iSCSI connections.
By default, the maximum number of connections in SPDK is defined by
MAX_ISCSI_CONNECTIONS as 1024.

However, the return value of the iscsi_get_connections method contains
a significant amount of information. In certain cases, only the number
of connections is required, and the overhead of parsing JSON becomes
a considerable burden, especially when there are numerous connections.

To address this issue, the rpc method iscsi_get_stats has been added.
When this method is used, only the count of connections in each state
will be provided, eliminating the need for detailed information parsing.
