Subject: [PATCH] Change: - fix #165 - introduce a sub variable
 nginx_upstreams.group - introduce a sub variable nginx_upstreams.port - if
 upstream.group is define, it'll loop over a given group - if upstream.group
 isn't define, upstream.servers is still mendatory - the user can set an
 optional port at nginx_upstreams.port
