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 command naming caused problems when other parts of the service were
being altered. The parser doesn't seem to handle the case of overlapping
commands that well.
Updated test cases with new code and adjusted syntax accordingly.
Extended the test to cover modifications to readconnroute as well as do
checks on detection of invalid parameters.
Also allowed modifications to router_options at runtime.
