In order to save quite some time during the role execution, we apply run_once when defining /etc/hosts content. While this good for "static" content which is based on the inventory, resolving openstack_host_custom_hosts_records once may lead to unexpected behaviour. For instance, if host record depends on some specific group or other variables defined in host/group variables. In order to resolve it accordingly, we merge status and custom records together in blockinfile, which allows to resolve record individually for each host and not having penalty for most usecases.
