- currently you're forced to define extra states if you opt to install nginx with passenger,
 if you want the same outcome for passenger and nginx installs with equivalent config
- passenger is an extra module on top of nginx, makes no sense to end up with less configuration by default

(...) for snippets filename.
BREAKING CHANGE: Users have to modify their pillar
according to this commit. Users MUST append '.conf' for their
existing managed snippets.

First implementation of TOFS for:
nginx_config, passenger_config, servers_config and snippets
Introduced tplroot on modified files as well
Fixed GH link of nginx.conf file in docs/TOFS_pattern.rst
Fixed test for snippets name pillar

* Route all to `nginx/deprecated.sls`

BREAKING CHANGE: all previous `nginx` based configurations must be reviewed;
`nginx.ng` usage must be promoted to `nginx` and any uses of the original
`nginx` will have to be converted.

With this one can now also write

 - include:
   - file1
   - file2

Rather than only

 - include: file1
 - include: file2

on openSUSE Leap 15.0, the string was systemd.cpython-36

like openSUSE and SLES

to reduce duplication of constants

... by providing a pillar string. I developed this for use in
combination with ext_pillar and file_tree to deploy letsencrypt
certificates.

default value if dhparam isn't defined in the pillar.

Improvement - Disable reload of nginx when enabled=False (previously the nginx was always reloaded if settings.config != None; even with enabled=False)
