See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
The test appears to hang when the `SET sql_log_bin = 0` statement is
executed. Removing this seems to fix it and is OK as that's not what the
test aims to check.
Timing out the statements and adding a LIMIT clause to the DELETE
statement should rule out backend server related problems. If the test
still times out, the problem is most likely in MaxScale.
