* 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

Proper disabling of the default vhost

enable mod_ssl on Redhat

Removing the file /etc/apache2/sites-available/000-default.conf leads to an error when Apache is restarted.
So the symlink in /etc/apache2/sites-enabled/ should be removed, the actual file can stay.

Add custom port to RedHat config

Add mod_security management

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

Added the ability to remove the vhost file from debian

- This is then ignored by Apache

Manage ports.conf file properly

Cleanup whitespace in generated vhosts

Correct handling of allow encoded slashes

Allow to configure several interfaces for a vhost.

This is done by split the interface pillar value instead of using a proper
list so it behaves exactly the same as before for simple 1 interface cases
(no need to refactor one's pillar files).

The resulting is something like:

  Listen 1.2.3.4:80
  Listen [2001:abc:def:100::3]:80

  <VirtualHost 1.2.3.4:80 [2001:abc:def:100::3]:80>
  ...

allow AllowEncodedSlashes directive in vhosts.

Apache2 docs state this is global, but vhost overrides it even when not specified.

additionally, this directive is defaulted differently across distributions (eg. CentOS is default 'On')

this change allows control of the directive.

Allow global directives to be added to apache config

Added state for configuring logrotate

Add mod_dav_svn support
