[libvirt] [PATCH v7 1/8] parallels: add driver skeleton



Parallels Cloud Server is a 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.

This first patch adds driver, which can report node info only.

Signed-off-by: Dmitry Guryanov <dguryanov parallels com>
---
changes in v7:
  * renamed to 'parallels', because first, the product renamed to
    "Parallels Cloud Server" and there are other products, such
    as Parallels Workstation for linux, which this driver will
    be able operate.
changes in v6:
  * Add info about PVS to commit message
  * fixed issue with POTFILES.in
  * fixed check in configure
  * check for prlctl command existence moved to pvsRegister
changes in v5:
  * add me to AUTHORS
  * fix indent in preprocessor directives in pvs_driver.h
  * remove unneded include
  * remove pvs_driver.c from po/POTFILES.in
