Changes in preparation for the m2 model

1) Replace enum 'ControlLoopTargetType' with 'String' -- symbols such as
   'ControlLoopTargetType.VM' still work, but now expand into a String.
   This gives the ability to add new application-specific types.

2) Move 'ControlLoopEvent.payload' to 'VirtualControlLoopEvent'. This
   symbol isn't common to all 'ControlLoopEvent' types, and this
   definition collides with a 'payload' defined in our application.

3) Add 'RestManager.patch(...)', which performs a REST patch.

4) Add lombok getters and setters

5) Remove trailing spaces

6) Fix order of arguments in 'assertEquals' in 'ControlLoopTargetTypeTest'

7) Update Junit tests in 'RestTest' to include 'RestManager.patch(...)'
