Added TODO that will fix an issue with restoring to non-default
directories (VE_ROOT and VE_PRIVATE) and the vz config still
pointing to the old directories
vzpbackup: Added variables for the commands to be called and
           explicitly set them. Needs to be amended if installation
           is different from default CentOS install

vzprestore: Added option (--vzdir) which allows to specify the directory
            the container will be restored to. This will override the
            default setting in /etc/vz/vz.conf.
Removed --vzdir TODO
Merged upstream changes
