Turned on checkstyle but turned off line length for sql because
now is not the time. That caught a few things like redundant
modifiers, out of order modifiers, and multiple top level classes
per file. Fixing them gave me a great little tour. So I'm going to
go and do the same in the plugin code now.

Big change here is that we start to use ES's base test clases for
testing. This should give us access to randomized testing and makes
sure that the reproduction lines are correct.
Original commit: elastic/x-pack-elasticsearch@bcab64a028
Make the projects more like the rest of Elasticsearch:
* Move integration tests from `itest` to `test`
* Make a build file per sql subproject
* Make sql work properly with elasticsearch-extra
