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
This is needed to kick off undercloud install with
--use-heat option. This includes new config options
to configure containerized undercloud along with
existing instack options.
Partially-implements: blueprint heat-undercloud
