refactor: migrate batch search to AMQP

[ClemDoum]

Depends on #1079, #1081 and #1283

At the end of this story, BatchSearchLoop and BatchDownloadLoop should be the same.

• [x] do #1283 to make it easier for this story
• [x] refactor Event -> Message
• [x] remove BatchDownloadCleaner from BatchDownloadLoop and any specific batch download coupling then rename class
• [x] use TaskView<T> for sending batch search to worker(s)
• [x] use TaskManager.startTask(String id, String taskName, User user) like BatchDownload
• [x] use TaskRunnerLoop for batch search
• [x] adapt error handling with batch search (repost, dead letter queue) in TaskRunnerLoop
• [x] remove method startTask(Callable<V> task, ...) to use same methods as BatchDownload and BatchSearch
• [ ] implement AMQP for BatchSearch
• [ ] use AMQP for working queues between SCAN, INDEX, NLP (full redis, full AMQP, full memory) if possible
• [ ] manually test non regression with memory, Redis, AMQP
