Description of problem: Deployment of hosted engine should work in IPv6-only scenarios.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Install ovirt-hosted-engine-setup ovirt-engine-appliance
2. Disable IPv4 and enable IPv6
3. hosted-engine --deploy


Actual results:
Deployment fails in multiple steps 

Expected results:
Deployment succeeds.

Additional info:
https://gerrit.ovirt.org/#/c/93367/ highlights the code locations which has to be modified for IPv6 support.
Additional to this changes, IPv6 has to be enabled in
libvirt's default network, which is used for the temporary VM:

echo 2 > /proc/sys/net/ipv6/conf/eth0/accept_ra
systemctl start libvirtd
virsh net-edit default
# add the line
# <ip family='ipv6' address='fd00:1234:5678:900::1'
prefix='64'/>  
virsh net-destroy default
virsh net-start default

The IPv6 address in libvirt's network is not important, it is only
important to enable IPv6.

The host has to be configured using a static IPv6 address, e.g.:

echo "fde4:e66c:9a7c:dd91::2 ipv6test9" >> /etc/hosts
echo "fde4:e66c:9a7c:dd91::3 hengine.local" >> /etc/hosts
echo IPV6INIT="yes" >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo IPV6ADDR="fde4:e66c:9a7c:dd91::2/64" \
  >> /etc/sysconfig/network-scripts/ifcfg-eth0  
echo BOOTPROTO="none" >> /etc/sysconfig/network-scripts/ifcfg-eth0
echo IPV6_AUTOCONF="no" >> /etc/sysconfig/network-scripts/ifcfg-eth0
systemctl restart network

The only difference is that 1372134 has been opened downstream specific.
