Jesse Pretorius b98100fe0c Ensure that services restart in a particular order
Currently when multiple services share a host, the
restart order is random. This is due to an unordered
dict being used to facilitate the mapping of services
to their groups, names and other options.

Based on [1], this patch implements changes to the role
to ensure that services on the same host are restarted
in the correct order when the software/config changes.
