update erlasticsearch to take json docs

Updated erlasticsearch drivers to track dieswaytoofast/master, which had tag on effects w/ thrift and jsx.
Note that I don't know where else jsx is used, and consequently, while these _are_ point releases for jsx (1.4.1 to 1.4.3), I dunno what might have broken

Also, in cloudi_services_databases, I had to re-add 
`{lib_dirs, ["..", "../../external", "../../external/nodefinder", "../../external/zeromq/v3"]}.`
in rebar.config, without which the tests wouldn't run (for me at least)

* json docs must be jsx-able
* updated jsx version to 1.4.3
* updated thrift to support jsx 1.4.3
