qemu command option 'hostcache' added to -drive for block devices.
While starting a VM from qemu commandline, this option can be used

use of 'hostcache' and 'cache' options not allowed.

I'm not sure if introducing this alone makes sense. I think I would only
do it when we introduce more options that allow replacing all cache=...
options by other parameters.
Can we do transition to alternatives for 'cache=' in a phased manner?
Until all other params are ready, we can allow hostcache (as well
as other params as and when they are ready) in cmdline with the
condition that 'cache=x', if specified, overrides these params.
Once we have all other params ready, 'cache=' can be replaced completely.
thanks, Supriya
