Fix: #36520

Summary

The part of the 24702 story.

The moving average pipeline aggregation has been deprecated as of 6.4: https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-pipeline-movavg-aggregation.html

We need to replace it with the new Moving Function aggregation instead.

The changes replace Moving Average Aggregation by the Moving Function Aggregation

                "the_movavg": {
                    "moving_avg":{
                        "buckets_path": "the_sum",
                        "window" : 30,
                        "model" : "holt_winters",
                        "settings" : {
                            "type" : "add",
                            "alpha" : 0.5,
                            "beta" : 0.5,
                            "gamma" : 0.5,
                            "period" : 7
                        }
                    }
                }

Following params:

                "the_movavg": {
                    "moving_fn": {
                        "buckets_path": "the_sum",
                        "window": 10,
                        "script": "if (values.length > 5*2) {MovingFunctions.holtWinters(values, 0.3, 0.1, 0.1, 5, false)}"
                    }
                }

Following differences for existing visualizations

Settings for Exponentially weighted, Holt-Linear, Holt-Winters models are partially affected. It means that alpha, beta, gamma, period have been reseted to default values.

// Default values
metric.alpha = 0;
metric.beta = 0;
metric.gamma = 0;
metric.period = 1;
