Redis queue improvements

[louischan-oursky]

• Implement the Reliable Queues pattern https://redis.com/glossary/redis-queue/
• Write tests to show that Consumer does not stop when it encounters panic when processing tasks. (like http.Server)
• Add audit log when a task is enqueued, a task is dequeued, a task is completed.
