Eclipse was confused for two reasons:
1. `:x-pack:plugin` depended on itself.
2. `ql`, `sql`, and `eql` couldn't see some methods.
I fixed problem 1 by only adding the "depends on itself" configuration
outside of eclipse. I fixed problem 2 by making a `test` sub-project in
`ql` that contains test utilities and depending on those where possible.
