Description of problem:
hypervisor_id="hwuuid" is only applicable to esx and rhevm, so no need to list hwuuid for other hypervisors when create configuration by virt-who configure plugin.

Version-Release number of selected component (if applicable):
satellite-6.5.0-6.beta.el7sat.noarch

Actual results:
uuid, hostname and hwuuid are listed for all hypervisors when create configuration.
