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.
From 10.1.32, 10.2.14 and 10.3.6 onwards, there is an
information_schema plugin called DISKS using which information
about the disk space situation on the server can be obtained.
Subsequent commits will add configuration options for specifying
limits and take the functionality in use in monitors where it makes
sense.
