a new manual command. The commands are now checked every 100 ms.

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.

Monitor json diagnostics printing cleanup
...
The 'events' and 'script' config values were defined for every monitor.
Removed the extra definitions and moved the variables to MXS_MONITOR.
MariaDBMonitor was printing config values a second time, they are
already printed by the caller.
Moved the events enum definition to the internal header since it's no longer
required by modules.
Added a default config setting "all" to 'events' to clarify that it enables
all events.

Move execute_worker_task into mxs::Worker

The function has use outside of the monitors as it makes execution of
worker tasks much more convenient. Currently, this change only moves the
code and takes it into use: there should be no functional changes.

Construct diagnostics results in the monitor thread
...
MariaDBMonitor diagnostics printing is unsafe as some of the read
fields are arrays. To be on the safe side, the fields are now read
in the monitor worker thread.
Since diagnostics must work even for stopped monitors, a worker task
is used. In practice, it usually runs when the monitor is sleeping.
