[PATCH v10 6/9] parallels: add support of VNC remote display

[Dmitry Guryanov <dguryanov@xxxxxxxxxxxxx>]

Add support for reading VNC parameters of the VM.

Signed-off-by: Dmitry Guryanov <dguryanov@xxxxxxxxxxxxx>
---
Changes in v10:
  * prlctl now doesn't print vnc service port in auto mode
    if VM is not started, fix it here.
  * handle manual vnc mode
  * add listen address
