 - Added property `ActionName` to all `xxActions` input types so user can specify a name per action. If not provided, service will generate a name.
 - Added property `ActionName` to all `xxActionResult` output types that displays the name of each action.
 - Added suppport for multiple actions of the same type.
 
-### Breaking Changes

 ### Bugs Fixed
 - `AnalyzeActionsOperation.GetValuesAsync()` and `AnalyzeHealthcareEntitiesOperation.GetValuesAsync()` are now validating that the operation has completed successfully before attempting to return any values. An `InvalidOperationException` is thrown if this is not true.
