This patch replaces code, which creates domains by
running prlctl command.

prlsdkCreateVm/Ct will do prlsdkApplyConfig, because
we send request to the server only once in this case.

But prlsdkApplyConfig will be called also from
parallelsDomainDefineXML function. There is no problem with
it, parallelsDomainDefineXML will be refactored later.
