[PATCH 5/8] parallels: add a new vz connection driver and hypervisor structures

[Maxim Nestratov <mnestratov@xxxxxxxxxxxxx>]

We add this connection driver just as an exact copy with different
name to keep backward compatibility.
Vz stands for Virtuozzo, which is a new name of Parallels Cloud Server.
