Hammer CLI

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1470014
Description of problem:
Currently there isnt a way of listing the global parameters of particular host using hammer. Neither in host info nor any separate option is available for that.

So this RFE is to add the ability to list the global parameters of each host through hammer.

Version-Release number of selected component (if applicable):
Satellite 6.3 snap 5 (Can be added to all previous sat versions 6.1 and 6.2)

How reproducible:

Steps to Reproduce:
1. Create host that will inherit the global parameters from parent component
2. List all the global params for that host through hammer.

Actual results:
No way of listing global params for perticular host through hammer

Expected results:
Add ability to list global parameters for each host in hammer
