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 tests can now wait for a number of monitor intervals. This removes the
need to have hard-coded sleeps in the code and makes monitor tests more
robust under heavier load.
Added some helper functions into the MaxScale class and default parameters
into the connection creation functions. Also made the ip() function const
correct.
