Changes to support multiple outputs from a state

This review addresses two main changes:
1) inputFields and outputFields are not tied to task definition anymore.
   Instead inputEvent and outputEvents associated to a task is populated
   as part of the policy state definition, as the state definition have
   the information anyway.
   - Clean up of the usage of inputFields and outputFields in task
     definition will happen in a future review
   - inputFields and outputFields defined in task definition in
     policies until honolulu will not make the policy invalid as the
     changes are done in backward compatible way.
2) Multiple output events can come out of a final state now.
   - Define another policy state output with the relevant eventName in
     the command file
   - In the task logic, create a map to store the fields of the relevant
     outputEvent, and then just call
     "executor.addFieldsToOutput(<the_map_of_fields>)"
     These 2 steps are enough to send multiple events to relevant
     components as per the apex configuration.
