    block: Remove "options" indirection from blockdev-add
    
    Now that QAPI supports boxed types, we can have unions at the top level
    of a command, so let's put our real options directly there for
    blockdev-add instead of having a single "options" dict that contains the
    real arguments.
    
    blockdev-add is still experimental and we already made substantial
    changes to the API recently, so we're free to make changes like this
    one, too.

Sorry for the confusion!  Early adopters always have the most fun ;)
