Subject: Switch to freertos timers (#1095)

* Use FreeRTOS timer for AlarmController
* Use FreeRTOS timer for MotorController
* Remove app_timer component from compilation as we now solely use
  FreeROTS timer
* Simplify variable and text names for AlarmController and MotorController timers
* Call ScheduleAlarm directly from StopAlerting, for recurring timers
