The full apache context variable can grow quite large if using multiple
vhosts with SSL certificates.
With 200 sites the apache variable is being rendered 200 times which resuls
in observed renderer output of about 950MB...
state.apply will result with MemoryErrors in such cases.
This PR modifies the templating code to _only_ use a per site context
and pass a trimmed down copy of the apache context instead of the full.
Drive-By: Correct indentation for context variables.
Drive-By: Remove duplicate map/apache functionality. Only use map.
FEATURE: Archlinux support
FEATURE: Windows support
FEATURE: Enhanced CI/CD
FEATURE: modular states

The current Red Hat config allows to set DefaultCharset to a value.
In certain situations it is necessary to leave it unconfigured thouguh.
Make the content optional, if the value of apache.default_charset is None,
the item is skipped. Otherwise it defaults to UTF-8.
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.
This fixes the following error when Jinja tries to process
`mpm_prefork.conf.jinja` or `00-mpm.conf.jinja`, when it processes the
`max_request_workers` comparison:
```
Unable to manage file: Jinja error: '>=' not supported between instances of 'str' and 'int'
[...]
<IfModule mpm_prefork_module>
StartServers {{ mpm_param['start_servers'] | d('5') }}
MaxRequestWorkers {{ mpm_param['max_request_workers'] | d('150') }}
{%- if mpm_param['max_request_workers'] | d('150') >= 256 %} <======================
ServerLimit {{ mpm_param['max_request_workers'] | d('150') }}
{%- endif %}
MinSpareServers {{ mpm_param['min_spare_servers'] | d('5') }}
MaxSpareServers {{ mpm_param['max_spare_servers'] | d('10') }}
MaxConnectionsPerChild {{ mpm_param['max_connections_per_child'] | d('0') }}
```
Add filters that convert the values to an int first.
