qmp: add set-numa-node command
Command is allowed to run only in preconfig stage and
will allow to configure numa mapping for CPUs depending
on possible CPUs layout (query-hotpluggable-cpus) for
given machine instance.
Example of configuration session:
$QEMU -smp 2 --preconfig ...
QMP:
-> {'execute': 'query-hotpluggable-cpus' }
<- {'return': [
{'props': {'core-id': 0, 'thread-id': 0, 'socket-id': 1}, ... },
{'props': {'core-id': 0, 'thread-id': 0, 'socket-id': 0}, ... }
]}
-> {'execute': 'set-numa-node', 'arguments': { 'type': 'node', 'nodeid': 0 } }
<- {'return': {}}
-> {'execute': 'set-numa-node', 'arguments': { 'type': 'cpu',
'node-id': 0, 'core-id': 0, 'thread-id': 0, 'socket-id': 1, }
}
<- {'return': {}}
-> {'execute': 'set-numa-node', 'arguments': { 'type': 'node', 'nodeid': 1 } }
-> {'execute': 'set-numa-node', 'arguments': { 'type': 'cpu',
'node-id': 1, 'core-id': 0, 'thread-id': 0, 'socket-id': 0 }
}

{'props': {'core-id': 0, 'thread-id': 0, 'node-id': 1, 'socket-id': 0}, ... }
