[pump-app] Add PCC Event example

[andersbangGF]

Problem

• The Pump Configuration and Control cluster supports a series of events that will be injected from the user application. This is not currently shown in the pump-app sample application.

Change overview

• Added en example of event posting from the pump-app controlled with the launchpad button
• Disabled unnecessary Wifi and Ethernet diagnostics clusters to free up enough FLASH to allow the app to build again.

Testing

*Built the pump-app for the TI platform and verified that there is enough memory for the app to link and run
*Tested on hardware. Commissioned pump-app on thread network and verified that the GeneralFault event is posted when the button is pressed.
