enhancement : attribut path_xxx and path.xxx

[goacid]

Attribut path.xxx must be set for configuration file.
Attribut path_xxx must be set to define deployment path
So same information in two differents ways :

elasticsearch_configure 'elasticsearch' do
  configuration ({
    'path.conf' => node['elasticsearch'][node.chef_environment]['path']['conf'],
    'path.data' => node['elasticsearch'][node.chef_environment]['path']['data'],
    'path.logs' => node['elasticsearch'][node.chef_environment]['path']['logs']
  })
  path_conf node['elasticsearch'][node.chef_environment]['path']['conf']
  path_data node['elasticsearch'][node.chef_environment]['path']['data']
  path_logs node['elasticsearch'][node.chef_environment]['path']['logs']
