Moving `domain_data`/apache config that is passed to jr_apache_vhost resources into `vhost['apache']`.
Use defaults from jr-apache cookbook.
Require jr-apache v0.1.6
Refactor in `prepare_vhost_apache` to make rubocop happy.

Also, `server_address` was not defined in `node['jr-apache']['default_domain_data']`.
Skip creating the file public path if the path is a symlink (e.g. to a NFS mount).
Merge branch 'jr_apache_vhost'
