Remove jest API which depends on Elasticsearch native API (also removed), so no longer depend on lucene for this scope. Replace such removed dependencies with the Elasticsearch low-level API, which does not depend on Lucene. That now used API is a REST client with minimal dependencies, indeed. -As opposed to Elastic's current high-level API, which still depends on lucene and other Gerrit-constraining libraries. Do so in order to decouple the elasticsearch client from lucene in Gerrit. That REST client does not logically require Lucene anyway. Most importantly, such decoupling now enables upcoming support for more than just one Elasticsearch server version. This includes the new possibility of bumping the latter to multiple yet later versions, such as 5 and 6.x. The currently used version (2.4) should also still be kept, for a while. Bumping such versions will likely require some Elasticsearch client code adaptations, so that Gerrit can (dynamically?) switch between either Elasticsearch server version to eventually support (hopefully soon). Doing the same for the elasticsearch tests in Gerrit is to be done using another change or more changes. Add a partial and customized fork of [1], based on [1]'s commit [2], to preserve the ability of building proper json requests for Elasticsearch. Put that forked json-generating code under a new 'builders' sub-package. There should be a possibility in some near future to consider removing that fork, based on potential progress such as the one proposed in [3]. Meanwhile, this fork shall be maintained to usual Gerrit quality levels.
