The RabbitMQ community and project recommend erlang 19.3.x for the best,
most stable, results. This change downloads the recommended version of
erlang [ https://www.rabbitmq.com/which-erlang.html ] from ESL and moves
the erlang packages for distros into a specific list installed only when
the ``rabbitmq_install_method`` variable is not set to "file".
