For GetQuote, delegate a request to Quote Generation Service.
Add property "quote-generation-socket" to tdx-guest, whihc is a property
of type SocketAddress to specify Quote Generation Service(QGS).
On request, connect to the QGS, read request buffer from shared guest
memory, send the request buffer to the server and store the response
into shared guest memory and notify TD guest by interrupt.
command line example:
qemu-system-x86_64 \
-object '{"qom-type":"tdx-guest","id":"tdx0","quote-generation-socket":{"type": "vsock", "cid":"2","port":"1234"}}' \
-machine confidential-guest-support=tdx0

Long line. Better:
# @quote-generation-socket: socket address for Quote Generation
# Service(QGS)
May I ask what's the limitation for qom.json? if 80 columns limitation
doesn't apply to it.
