The mod_ssl package name could be overridden in apache:lookup:mod_ssl.
Due to the way lookup keys are merged into the main apache dictionary,
the package name clashed with the mod_ssl configuration defined under
apache:mod_ssl.

Fix that by renaming the mod_ssl package variable to mod_ssl_pkg.

Drive-By: Add mod_ssl_pkg to the pillar.example file.

Document Stapling options in pillar.example

SUSE reads additional FLAGS that are used on the server start. They are
read from the APACHE_SERVER_FLAGS key, so we use a2enflag/a2disflag to
set those as we do with modules.

New behavior properly explained in pillar.example

Warning: changes directory.default when used with non-standard documentroot.
Now uses documentroot, instead of previously "default" documentroot path.

* [ssl] [debian] manage ssl.conf with pillars
* [apache] make cyphersuite a list
* [apache/ssl] switch back to strings, lists merge is not good

* No more if.
* Allow lookup to set default value for all docroot
* updated pillar.example

Support for DocumentRootUser and DocumentRootGroup

* Adding exclude_listen_directive option

* Updating Debian config

* RedHat: Made AddDefaultCharset Directive configurable

* Added description of apache:lookup:default_charset to pillar.example, sane default equals former hardcoded UTF-8

* Add ProxyRequests directive

This allows or prevents Apache httpd from functioning as a forward proxy server.
[See](https://httpd.apache.org/docs/current/mod/mod_proxy.html#proxyrequests).
The default action is off so I've set this a the default for this formula so it does not change the default behaviour.

* Add example pillar usage

* Add support for proxy pass target options

* Add example usage

Add gitignore, kitchen-ci files
Add some tests and documentation

True and False are not correct values for apache config

Sometimes it's necessary optimization in nginx+apache2 environment

By reassigning options with `blockreplace` at `/etc/apache2/conf-available/security.conf`, which is linked as conf-enabled by default on Debian packages

* Add apache version (2.2, 2.4) detection based on osfinger (defaults to 2.4).
* Version can be overridden in pillar (for Apache 2.4 on RHEL 6 for example)

Fix check for SSLCertificateFile, SSLCertificateKeyFile variables in vhosts/standard.tmpl, now using dict.get()

Add optional templating for the register site aspect of a pillar.

User can specify keys to be included as defaults, otherwise it is
treated as a normal managed file.

- Adding confext to virtualhost names.
- Renaming the default config file for Ubuntu (000-default.conf).
- Adding ability to use "Require all granted".

The structure of this example file was quite confusing. Most of these
values are not required and should be denoted as such. Jinja notiation
to denote re-used Pillar values was also a bad and confusing choice.

Closes #8

Having multiple different examples in the same file was causing
confusion.
