Temporarily leave the old node names in place with an override to 16g heap size, but pass the openstack_project default of 30g into the elasticsearch module as a new variable. Also don't actually configure the new servers to install and run elasticsearch yet, since there are manual steps needed to prep the additional block devices on them.
