Review differences in search body between Elasticsearch 2.x and 5. about elasticsearchdsl

It's good idea to handle this problem like that. It's too dangerous to make changes without deep knowledge of the problem. In this case I will cancel my opened pull requests for now.

@saimaz Hello! You tagged this issue as planned. Can you tell me when exactly do you want to work out this problem? This knowledge is really crucial for me, because I have planned migrating to ES 5.0, and this issue is blocking me. If you make the decission, I can help you with coding.

Hi @KnysakPatryk, I'm working on this. The plan is to release at least RC or even stable until 1st of January.

@saimaz I'm looking forward for this :)

@saimaz Hello in 2017! I hope you are doing well. How it's going with the library so far?

Hi @KnysakPatryk, Happy new 2017 year. I split elasticsearch version support to 2.x and 5.x. There is updated matrix table in the readme. First of all the focus is on 5.0 support since 2.x I assume is working well. Any help, by testing/contribution is very welcome ;)
