Since we now configure the bootstrap node for all roles (not only the controller) we have a problem if you need to remove the "0" node in any role, as we've got a hard-coded value that affects selection of the bootstrap node for all roles:
https://github.com/openstack/tripleo-heat-templates/blob/master/overcloud.j2.yaml#L234
input_values:
bootstrap_nodeid: {get_attr: [{{role.name}}, resource.0.hostname]}
bootstrap_nodeid_ip: {get_attr: [{{role.name}}, resource.0.ip_address]}
We need some way to change this index when replacing node "0", or another way to detect the first node in the group without using the node name (this looks like an index but I think it's referring to the resource name in the resource group, so it should be e.g "1" after this removal, ideally we'd use a list lookup here instead, perhaps that's a possible way to fix this).
