Let modules decide if they want to be reloaded. 

At times it seems relevant that worker their modules should not
be reloaded when receiving a SIGHUP. Developers can now control
this by returning anything else but KORE_RESULT_OK from their
initialization methods.

The parent module will always be reloaded.
