The current docroot ist set to /var/www. This is incorrect.
Fix with correct value /var/www/html.

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.

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

Makes it easier to clean any unwanted sites

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

unless test -d on file.directory seems useless.

Support for DocumentRootUser and DocumentRootGroup

Adapted log format to Apache's new default

Other states in this formula allow changing the Apache httpd or module

SCL to install newer versions than in the base repositories.  This
changes the apache.mod_ssl SLS to match them.
