monitor: add query-vnc-servers command
Add new query vnc qmp command, for the lack of better ideas just name it "query-vnc-servers". Changes over query-vnc: * It returns a list of vnc servers, so multiple vnc server instances are covered. * Each vnc server returns a list of server sockets. Followup patch will use that to also report websockets. In case we add support for multiple server sockets server sockets (to better support ipv4+ipv6 dualstack) we can add them to the list too.
