Commitcf869d5317"qmp: support out-of-band (oob) execution" made "id" mandatory for all commands when the client accepted capability "oob". This is rather onerous when you play with QMP by hand, and unnecessarily so: only out-of-band commands need an ID for reliable matching of response to command. Revert that part of commitcf869d5317for now, but have documentation advise on the need to use "id" with out-of-band commands.
