Description of problem:
running virt-who with "--hyperv" option by CLI, and then set other options to other modes, such as "--esx-owner, --esx-env, --esx-server, --esx-username, --esx-password", virt-who still can work, that means it will not check all the parameters consistency.

Version-Release number of selected component (if applicable):
virt-who-0.18-1.el6.noarch
subscription-manager-1.18.5-1.el6.x86_64
python-rhsm-1.18.5-1.el6.x86_64


How reproducible:
always

Steps to Reproduce:
1. run virt-who with an wrong parameter, such as "--hyperv" with "--esx-owner, --esx-env, --esx-server, --esx-username, --esx-password": 

# virt-who --hyperv --esx-owner=Default_Organization --esx-env=Library --esx-server=10.73.5.208 --esx-username=Administrator --esx-password=Welcome1 -d  -o

Actual results:
virt-who only check "--hyperv" parameter, ignore to check other parameters are matched or not.

Expected results:
virt-who should check all the parameter consistency
