qapi: Report support for -device cpu hotplug in query-machines
For management apps it's very useful to know whether the selected
machine type supports cpu hotplug via the new -device approach. Using
the presence of 'query-hotpluggable-cpus' alone is not enough as a
witness.
Add a property to 'MachineInfo' called 'hotpluggable-cpus' that will
report the presence of this feature.
Example of output:
{
"hotpluggable-cpus": false,
"name": "mac99",
"cpu-max": 1
},
{
"hotpluggable-cpus": true,
"name": "pseries-2.7",
"is-default": true,
"cpu-max": 255,
"alias": "pseries"
},
