…pers under certain conditions. (elastic#135431) This PR is an alternative of elastic#134996: This fixes a bug that would be triggered when we would downsample an index that had a metric field under a passthrough field. For example: ``` "metrics": { "type": "passthrough", "priority": 10, "properties": { "cpu_usage": { "type": "double", "time_series_metric": "gauge" } } } ``` In this PR, we extend the merging possibilities of a passthrough field to allow merging with object mappers that have subobjects false and they are not a root object. They also fix merging an object mapper with a passthrough field and ensure that the result will either be a passthrough field or an error if the objects are incompatible.
