New option will be used to allow commands, which are prepared/need to run, during preconfig state. Other commands that should be able to run in preconfig state, should be amended to not expect machine in initialized state or deal with it. For compatibility reasons, commands that don't use new flag 'allow-preconfig' explicitly are not permitted to run in preconfig state but allowed in all other states like they used to be. Within this patch allow following commands in preconfig state: qmp_capabilities query-qmp-schema query-commands query-command-line-options query-status exit-preconfig to allow qmp connection, basic introspection and moving to the next state. PS: set-numa-node and query-hotpluggable-cpus will be enabled later in a separate patches.
