From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: "Eduardo Lima (Etrunko)" <etrunko@redhat.com>
Date: Tue, 11 Apr 2017 21:47:44 -0300
Subject: [PATCH] Initial support for hosts

At the moment, we only care about the information about the cluster the
host is part of, and the list of the vms associated with it.
