Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means
the command allows out-of-band execution.
The "oob" idea is proposed by Markus Armbruster in following thread:
https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html
This new "allow-oob" boolean will be exposed by "query-qmp-schema" as
well for command entries, so that QMP clients can know which commands
can be used in out-of-band calls. For example the command "migrate"
originally looks like:
{"name": "migrate", "ret-type": "17", "meta-type": "command",
"arg-type": "86"}
And it'll be changed into:
{"name": "migrate", "ret-type": "17", "allow-oob": false,
"meta-type": "command", "arg-type": "86"}
This patch only provides the QMP interface level changes. It does not
contain the real out-of-band execution implementation yet.
