Beschreibung

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.

Research-Richtung
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.
