Rather than run every SQL test against multiple nodes we instead run a
subset of the tests simply for speed. The subset is both small but
exercises the CLI, JDBC, and REST interface and a few special "these
might be different in against multiple nodes" cases.
This drops the run time from of `gradle clean check` of these tests from
```
BUILD SUCCESSFUL in 4m 49s
```
To:
```
BUILD SUCCESSFUL in 2m 49s
```

This shuffles all of SQL's QA tests into the `qa/sql` directory, moving
some shared resources into the new `qa:sql` project. It also rigs up
testing of the rest SQL interface in all the sql qa configurations:
without security, with security, and against multiple nodes.
I've had to make some modifications to how we handle the audit log
because it has gotten pretty slow. If these modifications turn out to
not be fast enough then I'll change the test to querying the log files
and drop the audit log index entirely but the index seems to be holding
out for now.
