2. Top-level command for each parameter (e.g. block_set_hostcache).
Supported parameters are easily discoverable via query-commands. If
individual block devices support different sets of parameters then
they may have to return -ENOTSUPP.
I like the block_set approach.
Anthony, Kevin, Supriya: Any thoughts?
For the sake of overall QMP sanity, I think block_set_hostcache is
really our only option.
Ideally we should have blockdev_add, and blockdev_set would just take
the same arguments and update the given driver.
Ideally we'd have a backend_add, backend_set, etc.
But in the absence of that, we should provide the best interface we can
with the current tools we have.
For now, using high level commands is the best we can do.

But we don't have blockdev_add today, so whatever works for your as a
temporary solution...
