Describe the feature:

We want to give the users the ability to create breakdowns in ES|QL histogram mode. We decided to not go with inlinestats but keep the stats implementation and add a breakdown in the histogram component (exactly as in dataview mode) that it will update the underlying query on field selection

The latter is very important for the OneDiscover project. If we have the context, we want programmatically to breakdown the histogram with a specific field defined by the Discover app. We can't do it without inline stats support
