MXS-1220: Show parameters for services, filters and monitors

The service, filter and monitor resources now have a "parameters" value
which contains a set of all configuration parameters for that object. This
set contains both standard and non-standard parameters.

Also fixed a mistake in the constant name definitions for the monitor
parameters "events" and "script".
