[SSL] Sync new options for apache and nginx

Set the same options via apache[nginx]/files/_ssl.conf template for sites as
they were set by apache[nginx]/files/_ssl_secure.conf (deprecated) earlier.
By default the same set of ciphers was set in nginx and apache in _ssl_secure.conf
Now the same list of ciphers is set through pillar.
