Missing support for {dynamic_type}

[d2a-jbroek]

The API seems to be missing support for {dynamic_type} (https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-templates.html#template-variables)

In DynamicTemplate.Builder, I can't find any way to specify a mapping using {dynamic_type}. (Property.Kind has no corresponding value.)

Additionally, if I use the old RestHighLevelClient to create a mapping with {dynamic_type} and I then use the new client to get the TypeMapping (client.indices().get(request).get(indexName).mappings()), I get a MissingRequiredPropertyException.

co.elastic.clients.util.MissingRequiredPropertyException: Missing required property 'Builder.'

This is an issue in the API specification used to produce the Java code.

elastic/elasticsearch-specification#1558 has been opened to solve this, and the Java client will be updated once it's fixed.

This has been fixed in PR #292, backported to version 8.2 in PR #293 and to version 7.17 in PR #294.
