elasticsearch: Alert for no new docs on data nodes only

Browse source 
We can have nodes that are not masters, but don not hold any data. For example the client/coordinating nodes set up by the `stable/elasticsearch` helm chart:
https://github.com/helm/charts/tree/master/stable/elasticsearch#client-and-coordinating-nodes

And we can also have nodes being data and master nodes simultaneously.
So I think, this alert has to look for `es_data_node="true"` to be correct.
