It would be nice to also add a matching BlockdevOptionsIscsi to
qapi/block-core.json, to allow setting these structured options from
QMP. Separate patch is fine, but we need to do the work for ALL of the
remaining block devices eventually, and now that you are structuring the
command line is a good time to think about it.

Also, this requires passing the password in the command line. We
_really_ need to solve the problem of allowing the password to be passed
via a fd or other QMP command, rather than on the command line.
