* fix(redhat): use correct dirs for redhat family

Red hat family distributions do not implement sites-enabled nor vhosts.d
directories and all virtual hosts are under /etc/httpd/conf.d

Redhat based distros don't have /etc/init.d/httpd to rotate logs.
Default for them uses systemctl reload to rotate logs

The Suse family of distributions does not implement the sites-available/sites-enabled
distinction and puts all vhosts into /etc/apache2/vhosts.d.

BREAKING CHANGE: 'apache.sls' converted to new style 'init.ssl'
BREAKING CHANGE: "logrotate.sls" became "config/logrotate.sls"
BREAKING CHANGE: "debian_full.sls" became "config/debian_full.sls"
BREAKING CHANGE: "flags.sls" became "config/flags.sls"
BREAKING CHANGE: "manage_security" became "config/manage_security.sls"
BREAKING CHANGE: "mod_*.sls" became "config/mod_*.sls"
BREAKING CHANGE: "no_default_host.sls" became "config/no_default_host.sls"
BREAKING CHANGE: "own_default_host.sls" became "config/own_default_host.sls"
BREAKING CHANGE: "register_site.sls" became "config/register_site.sls"
BREAKING CHANGE: "server_status.sls" became "config/server_status.sls"
BREAKING CHANGE: "vhosts/" became "config/vhosts/"
BREAKING CHANGE: "mod_security/" became "config/mod_security/"

NOT-BREAKING CHANGE: 'config.sls' became 'config/init.sls'
NOT-BREAKING CHANGE: 'uninstall.sls' symlinked to 'clean.sls'

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.
