Alex Schultz 8de77cbe70 Add minion installation
Add the ability to install an undercloud minion which is connected to an
original undercloud. This minion can have either heat-engine or
ironic-conductor deployed on it.

Adds two new openstack commands for the minion install and a new
minion.conf can be used to configure them.

openstack undercloud minion install
openstack undercloud minion upgrade
