Add integration tests for executor properties

Added integration test that sets properties in a dummy plugin and amends
them in tasks in a policy. Variosu tests added to check combinations of
where properties are set in plugins or in tasks or both.

Implementaiton changed to:
- Always pass in a Properies object, the properties object coming into
  the policy cannot be null because the task/TSL/SFL may wish to set it
- Fix a bug where the properties were not passed from the ApexEvent to
  the engine event in the ApexEventUnmarshaller class

Issue-ID: POLICY-1743
