[PDI-8019] Updated ElasicSeach support for version 0.90.10 (curremt stable)

Hi,

I've updated the ElasticSearch APIs to current stable version 0.90.10.
Additionally, I've updated ElasticSearchBulk.java so that it handles data types (String, Date, BigNumber,Number and Boolean) correctly.
This is important, because only upgrading the API versions leads to wrong data,
when the bulk insert runs.

Regards
Martin
