Add parallelsDomainDefineXML function, it works only for existing
domains for the present.
It's too hard to convert libvirt's XML domain configuration into
PARALLELS's one, so I've decided to compare virDomainDef structures:
current domain definition and the one created from XML, given to
the function. And change only different parameters.
Only description change implemetented, changing other parameters
will be implemented later.
