MXS-1220: Add JSON return value to diagnostics entry points

Browse Source 
The modules that implement a diagnostics entry point now return a JSON
type object. This removes the need to format data inside the modules.

The module implementations of these are not yet complete which means that
MaxScale will fail to compile.
