Adrien Grand adf4712164 Make ip fields backward-compatible at query time. #18593
The fact that ip fields used a different doc values representation in 2.x causes
issues when querying 2.x and 5.0 indices in the same request. This changes 2.x
doc values on ip fields/2.x to be hidden behind binary doc values that use the
same encoding as 5.0. This way the coordinating node will be able to merge shard
responses that have different major versions.

One known issue is that this makes sorting/aggregating slower on ip fields for
indices that have been generated with elasticsearch 2.x.
