[PATCH 3/4] docs: add qemu-storage-daemon(1) man page |

Document the qemu-storage-daemon tool. Most of the command-line options
are identical to their QEMU counterparts. Perhaps Sphinx hxtool
integration could be extended to extract documentation for individual
command-line options so they can be shared. For now the
qemu-storage-daemon simply refers to the qemu(1) man page where the
command-line options are identical.

+QEMU Storage Daemon
+===================
+
+Synopsis
+--------
+
+**qemu-storage-daemon** [options]
+
+Description
+-----------
+
+qemu-storage-daemon provides disk image functionality from QEMU, qemu-img, and
+qemu-nbd in a long-running process controlled via QMP commands without running
+a virtual machine. It can export disk images over NBD, run block job
+operations, and perform other disk-related operations. The daemon is controlled
+via a QMP monitor socket and initial configuration from the command-line.
+
+The daemon offers the following subset of QEMU features:
+
+* Blockdev nodes
+* Block jobs
+* NBD server
+* Character devices
+* Crypto and secrets
+* QMP
+
+Commands can be sent over a QEMU Monitor Protocol (QMP) connection. See the
+:manpage:`qemu-storage-daemon-qmp-ref(7)` manual page for a description of the
+commands.
+
+The daemon runs until it is stopped using the ``quit`` QMP command or
+SIGINT/SIGHUP/SIGTERM.
+
+**Warning:** Never modify images in use by a running virtual machine or any
+other process; this may destroy the image. Also, be aware that querying an
+image that is being modified by another process may encounter inconsistent
+state.
+
+Options
+-------
+
+.. program:: qemu-storage-daemon
+
+Standard options:
+
+.. option:: -h, --help
+
+ Display this help and exit
+
+.. option:: -V, --version
+
+ Display version information and exit
+
+.. option:: -T, --trace [[enable=]PATTERN][,events=FILE][,file=FILE]
+
+ .. include:: ../qemu-option-trace.rst.inc
+
+.. option:: --blockdev BLOCKDEVDEF
+
+ is a blockdev node definition. See the :manpage:`qemu(1)` manual page for a
+ description of blockdev node properties and the
+ :manpage:`qemu-block-drivers(7)` manual page for a description of
+ driver-specific parameters.
+
+.. option:: --chardev CHARDEVDEF
+
+ is a character device definition. See the :manpage:`qemu(1)` manual page for
+ a description of character device properties. A common character device
+ definition configures a UNIX domain socket::
+
+ --chardev socket,id=char1,path=/tmp/qmp.sock,server,nowait
+
+.. option:: --monitor MONITORDEF
+
+ is a QMP monitor definition. See the :manpage:`qemu(1)` manual page for
+ a description of QMP monitor properties. A common QMP monitor definition
+ configures a monitor on character device ``char1``::
+
+ --monitor chardev=char1
+
+.. option:: --nbd-server
addr.type=inet,addr.host=<host>,addr.port=<port>[,tls-creds=<id>][,tls-authz=<id>]
+ --nbd-server
addr.type=unix,addr.path=<path>[,tls-creds=<id>][,tls-authz=<id>]
+
+ is a NBD server definition. Both TCP and UNIX domain sockets are supported.
+ TLS encryption can be configured using ``--object`` tls-creds-* and authz-*
+ secrets (see below).
+
+ To configure an NBD server on UNIX domain socket path ``/tmp/nbd.sock``::
+
+ --nbd-server addr.type=unix,addr.path=/tmp/nbd.sock
+
+.. option:: --object help
+ --object <type>,help
+ --object <type>[,<property>=<value>...]
+
+ is a QEMU user creatable object definition. List object types with ``help``.
+ List object properties with ``<type>,help``. See the :manpage:`qemu(1)`
+ manual page for a description of the object properties. The most common
+ object type is a ``secret``, which is used to supply passwords and/or
+ encryption keys.
