parallels: get domain info with SDK

Browse Source 
Obtain information about domains using parallels sdk instead of prlctl.
prlsdkLoadDomains functions behaves as former parallelsLoadDomains with
NULL as second parameter (name) - it fills parallelsConn.domains list.

prlsdkLoadDomain is now able to update specified domain by given
virDomainObjPtr.
