Reverted implementation of new parameter for `this.start()` by incrementing abaaso dependency, updating `this.restart()` to cache the configuration and pass it to `this.start()`, changed `TERMINATE` pseudo constant to `TERM_SIG` & created `TERM_CODE` to handle codes & signals, refactored `this.stop()` to kill workers from master so ps are not orphaned when `this.restart()` is executed
