- Some of the Transformation classes would initialize their Action's action_kind using the default (using Transformation constructor without an action_kind parameter). - Others, however, would use that constructor and initialize action_kind manually in their constructor, but setting the default value (RunTimeBeforeMatchAttemptKind = 1), which was redundant. - Removed unused Transformation constructor to specify action_kind. - Converted Action::Kind into an 'enum class' to require using the enum constants (instead of integer values, which are difficult to track in the codebase and change)
