block: Remove "options" indirection from blockdev-add

Browse source 
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.
