Currently the PutElasticSearch5 processor does not support external versioning.
The idea would be to add a property that follows the same logic as the Id property, and allows index documents with an externally controlled version.
I've changed the code already and added some tests. Right now the changes proposed are:
- Add a new property Version in the processor block.
- Change the Index operation to support the versioning number and versioning type = external
- Check if the versioning is used with other operation types, fail if so.
(Idea behind this is that the bulk api doest not support external versioning for any other operation except Index)
