Mark Goddard 0cd5b027c9 Fix RabbitMQ restart ordering

The host list order seen during Ansible handlers may differ to the usual
play host list order, due to race conditions in notifying handlers. This
means that restart_services.yml for RabbitMQ may be included in a
different order than the rabbitmq group, resulting in a node other than
the 'first' being restarted first. This can cause some nodes to fail to
join the cluster. The include_tasks loop was introduced in [1].

This change fixes the issue by splitting the handler into two tasks, and
restarting the first node before all others.
