haproxy.pp mail_cluster_nodes is shown in basic configuration

[NVitanovic]

Property mail_cluster_nodes is shown in basic configuration although it's set to be shown in advanced. Also the property requires to be populated with something in order to pass validation, but description says it should be empty in order to use all the nodes available. So this creates an issues if the user wants to leave the field empty.

Possible solution is to change the name of the property to for example mail_cluster_nodes2 then the field for the property is shown in advanced configuration and can be empty.

If the variable is renamed to mail_cluster_nodes2 file /etc/puppet/modules/atomia/templates/haproxy/haproxy.conf.erb needs to be updated specifically on line 117 to reference the new name of the variable.
