elasticsearch::non_util doesn't work properly

[ragazzid]

When using elasticsearch::non_util it doesn't allow app master to receive external connection since it binds the service to localhost only.

Scenario

Create an environment with two app instances (one app_master and one app)

To reproduce

• Enable the elasticsearch::non_util recipe
• Check the config generated on the non-app_master instance
• Try to open a connection from the non-app_master
• Issue the command sudo ss -lt | grep 9200 on the app_master, the bind will be to 127.0.0.1 instead of 0.0.0.0 or ::
