Set FollowSymLinks options in apache vhosts

Without FollowSymLinks option in vhost I get this error message in apache logs:

```
Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden: /usr/share/foreman/public/assets/application-60157ee362dadef8e1c5b73833bba06f.css
```
