• worker: Markers use now a dedicated key in redis instead of using a special Job ID.

• priority: priority is separeted in its own zset, no duplication needed

• feat(queue): add removeDeprecatedPriorityKey method

• refactor: change job method name update to updateData

ref faster priority jobs

• rate-limit: limit by group keys has been removed in favor
  of a much simpler and efficent rate-limit implementation.
• backoff: object mapping is replaced by single function
• compat: The compatibility class for Bullv3 is no longer available.
• The QueueScheduler class is removed since it is not necessary anymore.
  Delayed jobs are now handled in a much simpler and
  robust way, without the need of a separate process.
• failed and stalled events are now produced by the Worker class instead of by the QueueScheduler.
