Store latest metrics in "current" index for query based on latest values?

@ruflin; Keeping the ES bug in github is fine.

Meanwhile, I found a way to duplicate the metrics in the "latest" index by using a ES ingest pipeline to transform the "_id" with the ID of the sensor and "_index" field with "latest_metrics"

PUT /_ingest/pipeline/transform-latest-metric HTTP/1.1
{
    "processors": [ 
         { "script":{
              "lang":"painless",
               "inline":"ctx._id = ctx.sensor_id ?: ctx._id ; ctx._index = ctx.latest_index ?: ctx._index"}
    }]
}
