Descrizione

Describe the feature:

runtime_fields currently don't support range, e.g. date ranges, as data types (docs). This could be useful for analytical use cases that rely on durations.

Describe a specific use case for the feature:

An index may hold two or more fields that mark the start and end of a period, e.g. a session. There is currently no easy way to visualize such date ranges within Kibana using runtime_fields for experimental purposes, instead an index mapping would have to be deployed grabbing data from said date fields.

The feature requires extending the runtime field system in Elasticsearch to support range types. Review the runtime mapping implementation in the codebase, particularly the `RuntimeField` classes and `Lucene` integration. The issue comments (17 total) contain discussion on potential approaches and challenges. Examine existing range field support in indexed fields for reference. The implementation will involve adding a new runtime field type and ensuring it works with the query and aggregation frameworks.
