- 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
http section in nginx.conf is indented by default. To increase
readability format the variable nginx_extra_http_options with
the same indent for multiline string blocks. Therefore indent
needs not to be done in yaml.
Defining a new variable (defaults to empty) that allows users to define
extra configuration options in the top-level 'http' block.
This allows for (optionally) finer grain control.
For Debian systems both conf.d and sites-enabled should be included by default. Redhat systems have not been changed.
Issues came up using Kibana on Ubuntu as it installs kibana.conf in the conf.d folder.
