The docs include portions of the SQL tests and for that to work they
need to point to position of the tests. They use a relative directory
but relative to *what*? That turns out to be a fairly complex thing to
answer, luckilly, `index.x.asciidoc` defines `xes-repo-dir` which points
to the root of the xpack docs. We can use that to find the sql tests
without having to answer the "relative to what?" question in two places.

* Remove "overview". That is already covered in the index page.
* Write a basic getting started page.
* Fix the CLI startup instructions.

The keywords inside SqlBase are now sorted alphabetically - much easier
to read and update the docs
Original commit: elastic/x-pack-elasticsearch@5aa89c5950
Adds docs for the REST API, translate API, the CLI, and JDBC.
Next we need to add more example queries and documentation for our
extensions.
