[PATCH 2/8] qemu: monitor: Add handler for blockdev-reopen
Introduce the monitor code for using blockdev-reopen. For now we'll use
x-blockdev-reopen so that the interactions between qemu and libvirt
can be tested with the existing code.
Since the usage will be guarded by the for-now unasserted capability
we'll be able to change the called command when the command will be
stabilized.
