parallels: add driver skeleton

Browse Source 
Parallels Cloud Server is a cloud-ready virtualization
solution that allows users to simultaneously run multiple virtual
machines and containers on the same physical server.

More information can be found here: http://www.parallels.com/products/pcs/
Also beta version of Parallels Cloud Server can be downloaded there.

<pre>
parallels:///default (local access)
parallels+unix:///default (local access)
parallels://example.com/default (remote access, TLS/x509)
parallels+tcp://example.com/default (remote access, SASl/Kerberos)
