* Instances of this class will delegate all call except schuduleAtFixedRate to the
* passed in EventLoop which for testing purposes will be the EmbeddedEventLoop.
*
* Note that schuduleAtFixedRate will actually not run the command given to it, but instead
* just return a ScheduledFuture that is marked as successful.
