vmm: Support vhost-user-block via "--disks"

Browse Source 
Add a socket and vhost_user parameter to this option so that the same
configuration option can be used for both virtio-block and
vhost-user-block.  For now it is necessary to specify both vhost_user
and socket parameters as auto activation is not yet implemented. The wce
parameter for supporting "Write Cache Enabling" is also added to the
disk configuration.

The original command line parameter is still supported for now and will
be removed in a future release.
