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.
