docs/interop: Delete qmp-intro.txt

qmp-intro.txt is quite small and provides very little information
that isn't already in the documentation elsewhere.  Fold the example
command lines into qemu-options.hx, and delete the now-unneeded plain
text document.

While we're touching the qemu-options.hx documentation text,
wordsmith it a little bit and improve the rST formatting.

-                          QEMU Machine Protocol
-                          =====================
-
-Introduction
-------------
-
-The QEMU Machine Protocol (QMP) allows applications to operate a
-QEMU instance.
-
-QMP is JSON[1] based and features the following:
-
-- Lightweight, text-based, easy to parse data format
-- Asynchronous messages support (ie. events)
-- Capabilities Negotiation
-
-For detailed information on QMP's usage, please, refer to the following files:
-
-o qmp-spec.txt      QEMU Machine Protocol current specification
-o qemu-qmp-ref.html QEMU QMP commands and events (auto-generated at build-time)
-
-[1] https://www.json.org
-
-Usage
------
-
-You can use the -qmp option to enable QMP. For example, the following
-makes QMP available on localhost port 4444:
-
-$ qemu [...] -qmp tcp:localhost:4444,server=on,wait=off
-
-However, for more flexibility and to make use of more options, the -mon
-command-line option should be used. For instance, the following example
-creates one HMP instance (human monitor) on stdio and one QMP instance
-on localhost port 4444:
-
-$ qemu [...] -chardev stdio,id=mon0 -mon chardev=mon0,mode=readline \
-             -chardev socket,id=mon1,host=localhost,port=4444,server=on,wait=off \
-             -mon chardev=mon1,mode=control,pretty=on
-
-Please, refer to QEMU's manpage for more information.
-
-Simple Testing
---------------
-
-To manually test QMP one can connect with telnet and issue commands by hand:
-
-$ telnet localhost 4444
-Trying 127.0.0.1...
-Connected to localhost.
-Escape character is '^]'.
