Deprecate QMP cpu-add

Browse Source 
The intended functionality of QMP `cpu-add` is replaced with
`device_add` (and `query-hotpluggable-cpus`).  So let's deprecate
`cpu-add`.

A complete example of vCPU hotplug with the recommended way (using
`device_add`) is provided as part of a seperate docs patch.
