* Prior to Elasticsearch 6.x you could have multiple types per index. They acted as a discrimatory column but were often
* confused with tables. The fact that the mapping API's treated them as seperate entities did not help.
*
* The general guideline has always been to use a single type per index. Starting from 6.x this is also enforced.
* Some features still need to store multiple types in a single index such as Parent/Child join relations.
*
* Both `Parent` and `Child` will need to have resolve to the same typename to be indexed into the same index.
*
* Therefore in 6.x we need a different type that translates a CLR type to a join relation. This can be configured seperately
* using `.RelationName()`
